- Ability Estimation Under Different Item Parameterization and Scoring Models
- A Monte Carlo simulation study investigated the effect of scoring format, item parameterization, threshold configuration, and prior ability distribution on the accuracy of ability estimation given various IRT models. Item response data on 30 items from 1,000 examinees was simulated using known item parameters and ability estimates. The item response data sets were submitted to seven dichotomous or polytomous IRT models with different item parameterization to estimate examinee ability. The accuracy of the ability estimation for a given IRT model was assessed by the recovery rate and the root mean square errors. The results indicated that polytomous models produced more accurate ability estimates than the dichotomous models, under all combinations of research conditions, as indicated by higher recovery rates and lower root mean square errors. For the item parameterization models, the one-parameter model out-performed the two-parameter and three-parameter models under all research conditions. Among the polytomous models, the partial credit model had more accurate ability estimation than the other three polytomous models. The nominal categories model performed better than the general partial credit model and the multiple-choice model with the multiple-choice model the least accurate. The results further indicated that certain prior ability distributions had an effect on the accuracy of ability estimation; however, no clear order of accuracy among the four prior distribution groups was identified due to an interaction between prior ability distribution and threshold configuration. The recovery rate was lower when the test items had categories with unequal threshold distances, were close at one end of the ability/difficulty continuum, and were administered to a sample of examinees whose population ability distribution was skewed to the same end of the ability continuum.
- Adult learner satisfaction with web-based non-credit workforce training.
- Web-based training has become a billion dollar industry in the United States. Electronically aided learning is viewed by many companies as a cost-effective way to deliver the up-to-date, up-gradable job-related training that the industry is demanding. This study sought to examine the relationship between learners’ satisfaction with online training as it relates to learner readiness, online features, and course relevance. The population for this study was adults seeking non-credit workforce training, specifically library professionals who were involved in web-based training through the Lifelong Education @ Desktop (LE@D) program at the University of North Texas, Denton. Online methods of training are used most extensively in the area of mandatory or compliance training, in which 35 % of training is conducted mostly or completely online. The total potential library population using LE@D product to date is approximately 4,000 unique enrollments nationwide. Participants were selected from a complete list of unique LE@D users over a 90-day period. A survey instrument was sent via e-mail to 514 enrollees who had completed a recent LE@D online training course. In total, 254 participants responded to the survey. Bivariate analysis of the variables using the Pearson product-moment correlation was used to determine the occurrence and strength of a relationship between each of the three independent variables and the dependent variable in order to test the three research hypotheses. A regression model was used to explain how significantly the three independent variables, that is, online features, learner readiness, and course relevance, would have an impact on learner satisfaction. Results suggest that learner awareness of issues surrounding online features, learner readiness, and course relevance have a statistically significant impact on the overall satisfaction of the Web-based training event. As companies continue to adopt eLearning as a training investment, attention should be given to the end-users experiences. Employee responses to Web-based training are important because employee satisfaction is an indicator that a company’s training investment will result in positive outcomes.
- Analysis of leadership perceptions using multirater feedback.
- Performance improvement intervention begins with assessment. How that assessment is interpreted can mean the difference between success and failure. Previous research of 360-degree feedback instruments has tried to reconcile the differences between multiple rater groups. Rather than searching for agreement, this research proposes to understand the meaning of the differences using multirater feedback. Individuals determine ratings based upon their own perspective and building upon the understanding of rater perspective may result in improved assessments. Data from an existing data set was processed using a second-order CFA in structural equation modeling. Covariance between the second-order factors and rater groups determined the difference in how each rater group perceived the leader.
- Analysis of Perceptional Differences Among Department Chairs, Faculty, and Instructors Toward the Barrier to Using Multiple Teaching Strategies in Two-Year Technical and Community College Electronics Courses
- The purpose of this study was to identify and analyze perceptional differences among department chairs, faculty, and instructors toward the barrier to using multiple teaching strategies in two-year technical and community college electronics courses. The literature review focused on defining multiple teaching strategies and identifying and discussing four major perceived barriers to implementing them in the electronics classroom: student, resources, classroom environmental, and teacher training/teaching technology. The targeted population consisted of 150 out of 231 electronics teaching technical and community college department chairs, faculty, and instructors throughout the state of Texas. In actuality, the targeted population's breakdown consisted of 36 full-time electronics teaching department chairs, 96 full-time electronics teaching faculty and instructors, and 18 part-time electronics teaching faculty and instructors who were actively involved in the delivery of instruction in their respective schools. Analysis of the data revealed that: (1) there are no significant differences among the perceptions of department chair people, faculty, and instructors toward the four perceived barriers to implementing multiple teaching strategies in a post-secondary electronics program; and (2) there are no significant differences in the perceptions electronics faculty members categorized by years teaching experience toward each of the four perceived barrier categories to implementing multiple teaching strategies in a post-secondary electronics program. However, further research is needed to substantiate what other barriers exist that may have an impact upon utilizing multiple teaching strategies in two-year technical and community college electronics courses.
- An analysis of the characteristics of female juvenile offenders as predictors of resocialization or recidivism.
- Because there has been a paucity of research on the educational needs of females with academic, behavioral, and emotional problems involved with the juvenile justice system, this study has been an attempt to classify and compare specific characteristics of this population. In particular, it examined their demographics, disability prevalence rates, along with academic, behavioral, and emotional functioning levels, in order to further understand their relationship to the resocialization or recidivism of the different groups of female juveniles incarcerated in the state of Texas, and contribute to the research for further developing successful prevention and intervention programs. Various demographic factors of the female juveniles in this study were examined: (a) offender type, (b) county of commitment, (c) race/ethnicity, (d) age at first referral, and (e) English language proficiency. Prevalence rates of special education disabilities were determined. Academic functioning was measured by (a) IQ; (b) last school grade completed; (c) Test of Adult Basic Education (TABE) reading gain score; and (d) TABE math gain score. Behavioral functioning was indicated through (a) offense history, (b) documented behavior incidents, and (c) total risk score. Emotional functioning included DSM-IV diagnoses and treatment needs. Due to the design of the research being a descriptive exploration, the findings produced this compilation of attributes. The population of study typically reached an education level of 8th grade or less before becoming incarcerated. Their IQ is usually in the range of 80 to 90 points, with their reading and math achievement levels lagging about five years behind those of their age group. Their gains in reading and math are usually two to three levels per year. The female juveniles averaged 10 documented behavior incidents during their periods of incarceration. Their Global Assessment of Functioning (GAF) scores at intake showed they had moderate mental health symptoms and/or moderate difficulty in social, occupational, or school functioning. For this study population, there were almost twice as many recidivists as first-time offenders, and the findings showed that their characteristics, even those of different disability groups, were much more alike than different.
- Applying cognitive load theory to the design of online learning.
- The purpose of the study was to investigate the application of cognitive load theory to the design of online instruction. Students in three different courses (N = 146) were measured on both learning performance and perceptions of mental effort to see if there were any statistically significant differences. The study utilized a quasi-experimental posttest-only control group design contrasting modified and unmodified instructional lessons. Both groups were given a posttest to measure knowledge gained from the lesson (cognitive domain of learning) and perceptions of mental effort involved. Independent samples t-tests were used to compare the mean performance scores of the treatment groups (i.e. the sections using redesigned materials) versus the control groups for all three courses. Cohen's d was also computed to determine effect size. Mental effort scores were similarly compared for each group on the overall cognitive load score, for a total of six data points in the study. Of the four hypotheses examined, three (H1, H2, H4) found no statistically significant difference between the experimental and control groups. Negative significance was found between the experimental and control group on the effect of modality (H3). On measures of cognitive load, no statistically significant differences were found.
- Assessing Allied Health and Nursing Post-Secondary Career and Technical Education Teacher Attitudes and Beliefs About Reading
- This study examined allied health and nursing career and technical education (CTE) teacher beliefs and attitudes about reading. Since beliefs and attitudes influence the way teachers teach, it is important to understand what those beliefs and attitudes are, especially in relationship to reading in subject matter classrooms. One hundred twelve individuals responded to a written survey concerning their attitudes and beliefs about reading. A four-factor solution was achieved with a principal components factor analysis. A significant number of variables were associated with the factor labeled Reading Apathy, which appears to be indicative of the condition known as aliteracy among faculty who participated in the study. Professional development activities grounded in novice-to-expert theory are suggested as a way of overcoming the phenomenon. Recommendations for future research involve a more detailed study to further characterize the condition of aliteracy and its impact on student learning.
- Assessing the efficacy of learning communities at four north Texas community colleges.
- This observational study involving intact groups and convenient sampling examined learning communities at four North Texas Community Colleges. The purpose of this study was to determine if there was a significant difference in cathectic learning climate, inimical ambiance, academic rigor, affiliation and structure among students in learning communities and freestanding classes. Learning communities are gaining nationwide popularity as instruments of reform in Higher Education. Recent studies have discussed the benefits of learning communities to student, faculty and institutions. As learning communities are gaining popularity, especially at the community college level, there is a need to determine if the learning communities are significantly different than freestanding classes. The College Classroom Environment Scales, developed by Winston, Vahala, Nichols, Gillis, Wintrow, and Rome (1989), was used as the survey instrument for this study. Using SPSS 10.1, a multivariate analysis of variance, (Hotelling's T2) was performed on five dependent variables: cathectic learning climate (CLC), inimical ambiance (IA), academic rigor (AR), affiliation (AF), and structure (ST), which yielded a significant difference. The independent variable was learning community compared to freestanding classes (group). Follow-up independent t tests were also conducted to evaluate the differences in the means between the two groups and to explore which dependent variables contributed to the multivariate difference, which resulted in significant differences in inimical ambiance, affiliation and structure. The researcher concludes that learning communities make a difference for some learners, but not necessarily all and that more research needs to be conducted to find the answers to the questions concerning the efficacy and sustainability of learning communities in higher education.
- An assessment of technology learning styles, skills, and perceptions among teachers of grades pre-kindergarten through four.
- This study investigated whether a relationship exists between learning style and the self-reported technology-related needs, beliefs, stages of adoption, software expertise, and technology competencies of teachers in a large suburban school district. The Gregorc Style Delineator was used to identify dominant learning style, and the Snapshot Survey was used to measure technology-related needs, beliefs, stages of adoption, and software expertise. Technology competencies were measured using the Technology in Education Competency Survey. Data collected from 499 participants was included in data analysis. The study was conducted at each of the 12 elementary schools of a large suburban district in the Dallas-Fort Worth Metroplex. The findings suggest that there is a significant relationship between learning style and the technology-related needs, stages of adoption, software expertise, and competencies of teachers. The relationship between learning style and technology-related needs was significant at the p < .01 level. The relationships between learning style and technology-related stages of adoption, software expertise, and technology competencies were significant at the p < .05 level. Members of the abstract sequential [AS] learning style group reported having significantly fewer needs and significantly higher stages of adoption, software expertise, and competency than members of one or more of the other learning style groups. More research is recommended to determine whether these findings could be utilized to improve teacher staff development in the area of technology. Possible applications may include mentoring programs and the customization of training models to more closely match learning style profiles.
- Bias and Precision of the Squared Canonical Correlation Coefficient under Nonnormal Data Conditions
- This dissertation: (a) investigated the degree to which the squared canonical correlation coefficient is biased in multivariate nonnormal distributions and (b) identified formulae that adjust the squared canonical correlation coefficient (Rc2) such that it most closely approximates the true population effect under normal and nonnormal data conditions. Five conditions were manipulated in a fully-crossed design to determine the degree of bias associated with Rc2: distribution shape, variable sets, sample size to variable ratios, and within- and between-set correlations. Very few of the condition combinations produced acceptable amounts of bias in Rc2, but those that did were all found with first function results. The sample size to variable ratio (n:v)was determined to have the greatest impact on the bias associated with the Rc2 for the first, second, and third functions. The variable set condition also affected the accuracy of Rc2, but for the second and third functions only. The kurtosis levels of the marginal distributions (b2), and the between- and within-set correlations demonstrated little or no impact on the bias associated with Rc2. Therefore, it is recommended that researchers use n:v ratios of at least 10:1 in canonical analyses, although greater n:v ratios have the potential to produce even less bias. Furthermore,because it was determined that b2 did not impact the accuracy of Rc2, one can be somewhat confident that, with marginal distributions possessing homogenous kurtosis levels ranging anywhere from -1 to 8, Rc2 will likely be as accurate as that resulting from a normal distribution. Because the majority of Rc2 estimates were extremely biased, it is recommended that all Rc2 effects, regardless of which function from which they result, be adjusted using an appropriate adjustment formula. If no rationale exists for the use of another formula, the Rozeboom-2 would likely be a safe choice given that it produced the greatest number of unbiased Rc2 estimates for the greatest number of condition combinations in this study.
- Comparing outcome measures derived from four research designs incorporating the retrospective pretest.
- Over the last 5 decades, the retrospective pretest has been used in behavioral science research to battle key threats to the internal validity of posttest-only control-group and pretest-posttest only designs. The purpose of this study was to compare outcome measures resulting from four research design implementations incorporating the retrospective pretest: (a) pre-post-then, (b) pre-post/then, (c) post-then, and (d) post/then. The study analyzed the interaction effect of pretest sensitization and post-intervention survey order on two subjective measures: (a) a control measure not related to the intervention and (b) an experimental measure consistent with the intervention. Validity of subjective measurement outcomes were assessed by correlating resulting to objective performance measurement outcomes. A Situational Leadership® II (SLII) training workshop served as the intervention. The Work Involvement Scale of the self version of the Survey of Management Practices Survey served as the subjective control measure. The Clarification of Goals and Objectives Scale of the self version of the Survey of Management Practices Survey served as the subjective experimental measure. The Effectiveness Scale of the self version of the Leader Behavior Analysis II® served as the objective performance measure. This study detected differences in measurement outcomes from SLII participant responses to an experimental and a control measure. In the case of the experimental measure, differences were found in the magnitude and direction of the validity coefficients. In the case of the control measure, differences were found in the magnitude of the treatment effect between groups. These differences indicate that, for this study, the pre-post-then design produced the most valid results for the experimental measure. For the control measure in this study, the pre-post/then design produced the most valid results. Across both measures, the post/then design produced the least valid results.
- Comparison of Computer Testing versus Traditional Paper and Pencil Testing
- This study evaluated 227 students attending 12 classes of the Apprentice Medical Services Specialist Resident Course. Six classes containing a total of 109 students took the Block One Tests in the traditional paper and pencil form. Another six classes containing a total of 118 students took the same Block One Tests on computers. A confidence level of .99 and level of significance of .01 was established. An independent samples t-test was conducted on the sample. Additionally, a one-way analysis of variance was performed between the classes administered the Block One Tests on computers. Several other frequencies and comparisons of Block One Test scores and other variables were accomplished. The variables examined included test versions, shifts, student age, student source, and education levels. The study found no significant difference between test administration modes. This study concluded that computer-administering tests identical to those typically administered in the traditional paper and pencil manner had no significant effect on achievement. It is important to note, however, that the conclusion may only be valid if the computer-administered test contains exactly the same test items, in the same order and format, with the same layout, structure, and choices as the traditional paper and pencil test. In other words, unless the tests are identical in every possible way except the actual test administration mode this conclusion may not be applicable.
- Comparison of evangelical Christian children's God-concepts and logical thinking ability.
- God-concepts of 24 third to sixth grade evangelical Christian children were compared with the children‘s logical thinking abilities in a mixed-method study. Measurements included the Children‘s Interview and the Group Assessment of Logical Thinking (GALT). God-concepts among the children were Biblical, comforter, communicates, creator, empowering, protector, provider, purposeful, human characteristics, lives in heaven, male, counselor, God is Jesus, all-knowing, loving, perfect, powerful, real, and parental. The majority of concrete thinkers conceptualized God as a gracious guide. The majority of transitional thinkers viewed God also as a gracious guide as well as a distant divinity. Implications were given for religious educators to develop a model for age-appropriate instruction and curriculum and to equip parents to promote spiritual development with children at home.
- A comparison of traditional and IRT factor analysis.
- This study investigated the item parameter recovery of two methods of factor analysis. The methods researched were a traditional factor analysis of tetrachoric correlation coefficients and an IRT approach to factor analysis which utilizes marginal maximum likelihood estimation using an EM algorithm (MMLE-EM). Dichotomous item response data was generated under the 2-parameter normal ogive model (2PNOM) using PARDSIM software. Examinee abilities were sampled from both the standard normal and uniform distributions. True item discrimination, a, was normal with a mean of .75 and a standard deviation of .10. True b, item difficulty, was specified as uniform [-2, 2]. The two distributions of abilities were completely crossed with three test lengths (n= 30, 60, and 100) and three sample sizes (N = 50, 500, and 1000). Each of the 18 conditions was replicated 5 times, resulting in 90 datasets. PRELIS software was used to conduct a traditional factor analysis on the tetrachoric correlations. The IRT approach to factor analysis was conducted using BILOG 3 software. Parameter recovery was evaluated in terms of root mean square error, average signed bias, and Pearson correlations between estimated and true item parameters. ANOVAs were conducted to identify systematic differences in error indices. Based on many of the indices, it appears the IRT approach to factor analysis recovers item parameters better than the traditional approach studied. Future research should compare other methods of factor analysis to MMLE-EM under various non-normal distributions of abilities.
- A comparison of trainee and supervisor perceptions of transfer climate in a union-based training program.
- A supportive work climate is critical for successful transfer of learning. Influences in the work environment affect the trainee's ability to apply new skills to the job. The supervisor can be a significant figure in the trainee's perception of a supportive transfer climate. Little is known of the effect of supervisor participation in the training on transfer climate. The purpose of this study was to identify differences in trainee and supervisor self-perceptions of the factors affecting transfer climate. Additionally, this study examined the effects of supervisor participation in the training program on perceptions of transfer climate. The participants in this study were trainees in a union-sponsored instructor training program and their supervisors. The study found perception gaps between the overall perception of transfer climate and supervisor support. The level of supervisor participation in the training program was not to be a factor in the differences between the trainee and supervisor perceptions. No statistically significant difference exists in the perception of other transfer climate factors: supervisor sanctions, peer support, resistance/openness to change, and feedback/performance coaching. In addition, the study found that supervisor participation in the training made little difference in the perceptions of transfer climate by supervisors and trainees. Studies comparing trainee and supervisor perceptions of transfer climate and the effect of supervisor participation in the training on these perceptions are needed from other organizations before extensive generalizations can be made.
- A comparison of written composition assessment using standard format versus alternate format among college-bound students with learning disabilities and/or attention-deficit/hyperactivity disorder.
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to explore the efficacy of using a computer word processing program in the assessment of written expression with college-bound individuals who had been diagnosed with a learning disability (LD) and/or attention-deficit/hyperactivity disorder (ADHD). Fifty-six (35 eleventh and 21 twelfth) graders, attending a private college-preparatory school for students with LD and/or ADHD, were administered the Spontaneous Writing composite of the Test of Written Expression - Third Edition (TOWL-3). The TOWL-3 has equivalent forms, Form A and Form B. One form was administered in accordance with the test manual, using paper and pencil (standard format). The other form (i.e., alternate format) was administered with word processing access. Paired samples tests (repeated measure) and bivariate correlation designs were computed to explore the relationships between measures. Results of the study revealed significant increases (p<.01) in the subtest and composite scores when participants were administered the test in the alternate format. Other components of the research study did not reveal strong meaningful relationships when cognitive ability, graphomotor speed, and keyboarding rate were compared with the standard and/or alternative formats of the writing composite. A high rate of comorbity was exhibited with the majority of participants (75%) having two or more LD and/or ADHD diagnoses. On an informal questionnaire, the participants endorsed a strong preference for the use of word processors in the majority of their written academic tasks. The study concludes that for students who are accustomed to producing written work on a word processor, restriction from this writing tool can adversely affect the results of their product, leaving a false impression, underestimating their writing skills, ability, creativity, and subject knowledge. In addition, having access to a word processor during high stakes testing is paramount. Inaccurate results can affect future opportunities, such as admission to postsecondary educational settings. In summary, future and more extensive studies are needed to continue to increase the understanding of assessment, diagnosis, instruction, and assistive technology (AT) options for individuals with written language disorders.
- Cross-Cultural Validation of the Will, Skill, Tool Model of Technology Integration
- The teacher professional development component of the will, skill, tool model of technology integration was tested for predictive validity in the cross-cultural context of data from Texas, USA, and data from Mexico City, Mexico. Structural equation modeling (SEM) analysis, path analysis, and multiple regression analysis, were statistical procedures employed. The analyses yielded positive results for the model's validity and reliability. The resulting model was found to be a reliable tool to evaluate technology integration among elementary and middle school teachers in Texas and in Mexico City. For the purposes of this study, the teacher professional development component of the will, skill, tool model of technology integration is referred to as the will, skill, tool model of technology integration (WiSTTI). This was one of the seven alternative models tested for goodness of fit across a total of 7 data samples. The structural equation modeling approach proved to be a good technique to find the best fit model in a cross-cultural environment. Latent variables and a set of parameters to judge the validity and reliability of each model were set for testing and retesting in an iterative process. Eventually a "new" modified version of the WiSSTI model was found to fit the data for all samples studied from both countries. From a theoretical perspective, the variation of the WiSTTI model found to be the best fit to the data indicates that increased teacher willingness to integrate technology brings about increased skill, and increased skill leads to more advanced technology integration, if access to technology is available for instruction. Results derived from the model with respect to the evaluation of technology integration for teachers from Texas and Mexico City suggest a differential effect by country, with the Texas teachers (representing USA) currently more advanced in technology integration than their colleagues from Mexico. No large effect was found for educational level, with elementary school teachers and middle school teachers at approximately equivalent levels of technology integration in both countries.
- Current practices in working with special education paraeducators.
Access: Use of this item is restricted to the UNT Community.
With so many paraeducators working in special education, it is important for teachers, administrators, and researchers to know how paraeducators are being utilized, supervised, and managed in order to create the most effective programs for students with special needs. Research is needed regarding current practices in supervising paraeducators. The purposes of this study were to (a) delineate the current practices being utilized by special education teachers of students with emotional and behavioral disorders (EBD) who supervise paraeducators that work with students with EBD in the general education classroom and (b) determine how effective the supervised paraeducators perceive those practices to be. Current practices were revealed by answering the following questions: (1) According to special education teachers and paraeducators, what procedures and practices are being utilized to supervise paraeducators who work in the general education environment with students with EBD? (2) In what ways do teachers and paraeducators see these supervision practices as being effective? (3) What is the relationship between actual supervision practices and accepted best practices? There were 60 participants in all, 30 professional teachers and 30 paraeducators. All 60 participants completed a survey; of these 60, 5 teachers and 5 paraeducators were individually interviewed Findings from the study indicate that actual supervision practices of teachers do not represent the best practices found in the literature. The study found that each of the seven executive functions of supervision (orientation, planning, scheduling, delegating, training/coaching, monitoring/feedback, and managing the workplace) need additional attention from school districts in order to maximize paraeducator effectiveness.
- A deconstruction and qualitative analysis of the consumption of traditional entertainment media by elementary-aged children diagnosed with emotional disorders.
- This qualitative study examined whether a connection exists between children with emotional disorders consumption of traditional entertainment media and their subsequent vegative/anti-social classroom behavior. Research participants included six first-grade children diagnosed with an emotional disorder and their teacher. They were interviewed using a semi-structured approach. The students were observed in the natural setting of their classroom for a total of twenty-four hours, over a four-day period. Transcripts and classroom observations were analyzed, looking for connections between behavior and consumption of traditional entertainment media. Findings from this study concluded that these students used traditional entertainment media as a method of temporally escaping from the environment of their respective households.
- Descriptive Analysis of Comments Obtained during the Process of Regulating the Reauthorization of the Individuals with Disabilities Act of 2004
- This study examined the comments submitted by the public to the United States Department of Education (USDE), the Office of Special Education Programs, in response to the 2004 amended IDEA, prior to the development and publication of proposed regulations under 34 Code of Federal Regulations (CFR) parts 300 and 303 to implement programs under IDEA. Specifically, this study analyzed the types of individuals (e.g., parents, advocates, administrators, lawyers, support staff personnel) and interest groups along with the number of submissions, types of comments made, and specific provisions in the legislation that received the most comments during the period open to the public prior to the publication of the proposed regulations. In addition, an exploration of the existence of differences in comments submitted by states and regions was analyzed in terms of types of individuals, interest groups, types of comments, and specific provision of the 2004 amended IDEA. Content analysis approach utilizing qualitative data collection and analysis procedures was used for this study. The sample consisted of 2,199 comments submitted to the USDE via the U.S. Postal system, e-mail, and verbal testimony transcripts obtained during one of the public meetings held throughout the United States during the 60 day period open for commenting. The findings of this study revealed a large number of a particular type of respondent types, the majority of the comments were neutral in nature, and the largest percentage of comments received were directed at one particular section of the Act.
- Detecting the presence of disease by unifying two methods of remote sensing.
- There is currently no effective tool available to quickly and economically measure a change in landmass in the setting of biomedical professionals and environmental specialists. The purpose of this study is to structure and demonstrate a statistical change-detection method using remotely sensed data that can detect the presence of an infectious land borne disease. Data sources included the Texas Department of Health database, which provided the types of infectious land borne diseases and indicated the geographical area to study. Methods of data collection included the gathering of images produced by digital orthophoto quadrangle and aerial videography and Landsat. Also, a method was developed to identify statistically the severity of changes of the landmass over a three-year period. Data analysis included using a unique statistical detection procedure to measure the severity of change in landmass when a disease was not present and when the disease was present. The statistical detection method was applied to two different remotely sensed platform types and again to two like remotely sensed platform types. The results indicated that when the statistical change detection method was used for two different types of remote sensing mediums (i.e.-digital orthophoto quadrangle and aerial videography), the results were negative due to skewed and unreliable data. However, when two like remote sensing mediums were used (i.e.- videography to videography and Landsat to Landsat) the results were positive and the data were reliable.
- Distance Education in the Preparation of Special Education Personnel: An Examination of Videoconferencing and Web-based Instruction
Access: Use of this item is restricted to the UNT Community.
This study examined the effectiveness of employing videoconferencing and Web-based instruction in the preparation of special education personnel. Due to the acute shortage of special education personnel, it was anticipated that the use of videoconferencing and online instruction would provide a convenient way for students to attend class without having to travel to the actual location of the educational site. Further, it was believed that this initiative would result in higher student enrollment in special education teacher certification programs, consequently leading to an increase of personnel in the field. Moreover, the increase in personnel would enhance the ability of educational institutions to address the dismal academic, social, and behavioral outcomes of students with disabilities. Information for the study was collected from surveys that investigated how students perceived the use of videoconferencing and web-based instruction in the preparation of special education personnel. Ninety-four graduate students responded to the videoconferencing surveys while 88 responded to the Web-based instruction surveys. Six respondents were randomly selected to participate in face-to-face interviews designed to investigate the effectiveness of both approaches. Findings indicated that videoconferencing and Web-based instruction are convenient ways for students to attend class although videoconferencing sites may not be conveniently located to all learners. Furthermore, the effectiveness of these media depends on several factors: the instructor, the course structure, the learners' learning styles, the quality and quantity of interaction between learners and the instructor, and whether technological problems interfere with the learning process. The study determined that the more structured and organized the course, the more significant the learning outcomes. Also, the maturity level of the students lends itself to accountability toward achieving the desired learning goals. Technological problems and the lack of user-friendly technology lower the effectiveness of videoconferencing and Web-based instruction. Further research will be valuable in improving theories and approaches currently used in the application of videoconferencing and Web-based instruction in the preparation of special education personnel.
- The effect of an electronic evaluation questionnaire format on the return rate from field supervisors.
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to examine the usefulness of electronic-based questionnaires as a tool to gather data from field supervisors in the medical profession at various military bases. The study compared the response effects of an electronic evaluation questionnaire with the traditional method of paper-based questionnaires in gathering Level 3 data. The number of returns affects the amount of information available to the course personnel in creating a viable program that ensures the success of service members entering the occupational field and, ultimately, affecting the number of service members who remain beyond their first enlistment. The return rate and amount of missing data were tracked. Supervisors of graduates of a medical program who had observed service members for a minimum of 4-months were participants in the study. The z-test for comparing two proportions was used to determine significance of the study at the .05 level. Findings indicate that there was a significant difference in return rates and the amount of missing data when using the electronic format. Based on this study, the electronic-based questionnaire as a data-gathering tool provided a higher number of returns in a quicker time frame with fewer missing data in the technical training environment.

- Effect of individualized curricular accommodations, incorporating student interest and the impact on the motivation and occurrence/ nonoccurrence of disruptive behavior displayed by students with emotional/behavioral disorders.
- As a result of the reauthorization of the Individuals with Disabilities Education Act of 1997, schools must now consider positive behavioral interventions and strategies to address problem behavior of students with Emotional/Behavioral Disorders (E/BD). Given the poor behavioral, academic, and social outcomes for these students, there is a compelling need to identify effective, proactive interventions. Current literature has well established the ineffectiveness of traditional, punitive, and consequence-laden strategies to deal with behaviors. Research has shown the manipulation of antecedent stimuli, in the form of curricular adaptations, can provide a positive, proactive means of managing behavior. Specifically, curriculum modifications, based on student interest, are proposed as a positive, proactive strategy used to manipulate antecedent stimuli to improve the behavior of students with E/BD. The purpose of this study was to investigate the manipulation of antecedent stimuli through the implementation of individualized, curricular adaptations, based on student interest, to reduce the problem behavior of students exhibiting disruptive behaviors. A second purpose was to explore the effect of those adaptations on the behavior motivation of students with E/BD. In this study, curriculum modifications based on student interest were used to reduce disruptive behavior, increase desirable behavior, and effect change in the motivation for problem behavior among four elementary school boys with E/BD. Use of an ABAB reversal design, including interval data collection, and the use of a behavior rating scale and a motivation assessment scale were used to establish baseline data and determine effectiveness of the intervention. Results indicate that each student demonstrated a reduction in disruptive behavior, an increase in desirable behavior, and changes in motivation for behavior.
- The effect of professional development training for secondary mathematics teachers concerning nontraditional employment roles for females
- This quasi-experimental study, utilizing quantitative and qualitative descriptive methods, examined the sex-egalitarian attitudes of secondary mathematics teachers from the Ft. Worth Independent School District. A video tape, Women in the Workplace, was used as a training intervention to test the effectiveness of professional development training in altering the mathematics teachers' sex-egalitarian attitudes towards female employment. Information on the video presented seven jobs that provide opportunities for female students in the science, engineering, and technology fields that are considered nontraditional jobs for females. Subjects completed 19 Employment Role domain questions on the King and King (1993) Sex-Role Egalitarianism Scale. A one-way ANOVA was applied to the data to test for a significant difference in the means of the control group, who did not see the video, and the experimental group that viewed the video. Findings concluded that there was no significant difference in the sex equalitarian mean scores of the control group and the experimental group. The research indicated that it takes an intensive and prolonged training period to produce a significant change in people's attitudes. This study supports the research on length of training needed to change sex egalitarian attitudes of classroom teachers. There were data collected on four demographic areas that included gender, age, ethnicity, and years of teaching experience. A two-way ANOVA was applied to four demographic variables to test for interaction and main effect. A significant difference was found between the sex-egalitarian attitudes of male and female mathematics teachers' responses. There were no significant differences found in the sex egalitarian attitudes of secondary mathematics teachers when categorized by levels of age, ethnicity, and years of teaching experience. The information in this study should interest and benefit teachers, parents, students, administrators, and industry leaders.
- The effect of psychological type, economic status, and minority
- The purpose of this study was to determine if psychological type, economic status, and minority classification had an effect on the pass/fail rates of vocational nursing students. The rationale for conducting this study was based on the need for the institution to maintain program viability and successfully retain students. The personality types of vocational nursing students were measured using the Myers-Briggs Type Indicator. Measures of economic status and minority classification were obtained through subject self-report. Students enrolled in a vocational nursing program at a small North Texas community college were studied. The Chi-square Test of Independence with a 2 x 2 design was employed. Findings indicated that there was a statistically significant relationship between the pass/fail rates of thinkers versus feelers in the vocational nursing classroom. Findings did not indicate a statistically significant relationship between the pass/fail rates of extraverts versus introverts; sensers versus intuitives; or judgers versus perceivers in the vocational nursing classroom. Findings also suggested that there were no significant relationships between the pass/fail rates of individuals with poverty versus non-poverty economic statuses, nor between individuals with minority versus non-minority classifications. Based on this study, vocational nursing students psychologically typed as thinkers, may have lower passing rates in the vocational nursing classroom setting.
- The effects of a career education program on the career choices of fifth-grade students.
- The career development of students, demonstrated by students' career interest, is important for a more effective career education program. This study focused on the career choices of fifth grade students through the use of a career interest inventory before and after the use of a career education program. The design was experimental, and the purpose was to determine if there were differences in the career interest of fifth grade students who participated in a career education program compared with the career interest of fifth grade students who did not participate in a career education program. The COPS-PIC Picture Inventory of Careers (COPS-PIC) was used as a pretest and posttest for fifth grade students to determine baseline career interests. The COPS-PIC career inventory results were incorporated into the career education program and served as a career planning guide for incorporating students' input into career choices and exploration of those choices for a better understanding of the process of finding out who they want to be and what type of careers exists. The experimental group was provided instruction and career exploration opportunities for 4 weeks. The control group was not provided career education instruction and career exploration opportunities. This study suggests that fifth grade students who participated in a career education program were able to make more concentrated career choices at higher levels of interest after participating in the career education program. Additional studies that include the use of career interest inventories and a career education program are needed before extensive generalizations can be made.
- Effects of a simulation game on trainees' knowledge and attitudes about age-related changes in learning and work behaviors of older workers
- This investigation was conducted in response to the need for effective diversity awareness programs to help employers create intergenerational-friendly work environments. An experimental pre- and post-test control group randomized block design was employed to answer two research questions about the effects of a simulation game on knowledge and attitudes about age-related changes in learning and work behaviors of older workers. Participants were assessed immediately prior to and following the treatment, followed by a third assessment 60 days later. Necessary measures were taken to control for threats to the study's internal validity. An applicant pool comprised of human resource management and development practitioners and senior undergraduate students enrolled in human resource management courses yielded a sample of 65 participants. Chapter one introduces the study. Chapter two provides a review and summary of relevant literature on ageism in the workplace, training older workers, and simulation games. Chapter three describes the procedures and methods used to answer the research questions. Chapter four presents the results of all analytic procedures related to the investigation. Chapter five provides the conclusions and recommendations based on the findings of this investigation. In this investigation, the treatment group did not score significantly higher on their knowledge of age-related changes in learning and work behaviors of older workers than the control group following treatment. The attitudinal change experienced by the treatment group did not differ significantly from the attitudinal change experienced by the control group. Recommendations for further research include the following: (a) the disordinal interactive effect of the control group's performance on the knowledge measure during the 60-day interval between post assessments warrants further investigation, (b) the statistically significant change in attitude that occurred within each group during the 60-day interval following treatment warrants further investigation, and (c) more reliable instruments need to be developed for measuring the effects of heightened awareness following diversity interventions.
- The effects of ARCS-based confidence strategies on learner confidence and performance in distance education.
- The purpose of this research was to manipulate the component of confidence found in Keller's ARCS model to enhance the confidence and performance of undergraduate students enrolled in an online course at a Texas university using SAM 2003 software delivery. This study also tested whether the aforementioned confidence tactics had any unintentional effect on the remaining attention, relevance, and satisfaction subscales of the ARCS model as well as on learners' overall motivation for the class and the instructional materials. This study was conducted over a 5.5-week period with an initial sample of 81 total students. Two quantitative surveys were used to measure confidence and motivation: (a) the Course Interest Survey (CIS), and (b) the Instructional Materials Motivation Survey (IMMS). The results indicated that the treatment group showed statistically greater gains than the control group in terms of learner confidence on the CIS but not the IMMS. In terms of performance, the treatment group outperformed the control group on all of the individual posttest measures and on the overall aggregate mean performance score. The results showed no statistically significant difference on the attention subsection of the ARCS model. However, statistically significant differences were noted for the relevance and satisfaction subscales of the model. There was also a statistically significant difference in overall learner motivation as measured on both surveys. This research study suggests the feasibility of improving overall learner motivation and performance through external conditions such as systematically applied confidence tactics. The research further supports claims about the effectiveness of the ARCS model as a viable tool for enhancing online learner motivation and performance. What was unclear in this study was whether individual subsections of the ARCS model, such as confidence, can be independently manipulated.
- The Effects of Team Dynamics Training on Conceptual Data Modeling Task Performance
- Database modeling is a complex conceptual topic often taught through the use of project-based teams. One of the problems with the use of project-based teams in university courses is the determination of whether this is the most effective use of instructor and student time involvement and effort level. Therefore, this study investigated the impact of providing team dynamics training prior to the commencement of short-duration project-based team conceptual data modeling projects on individual data modeling task performance (DMTP) outcomes and team cohesiveness. The literature review encompassed conceptual data design modeling, the use of a project-based team approach, team dynamics and cohesion, self-efficacy, gender, and diversity. The research population consisted of 75 university students at a North American University (Canadian) pursuing a business program requiring an information systems course in which database design components are taught. Analysis of the collected data revealed that there was a statistically significant inverse relationship found between the provision of team dynamics training and individual DMTP. However, no statistically significant relationship was found between team dynamics training and team cohesion. Therefore, this study calls into question the value of team dynamics training on learning outcomes in the case of very short duration project-based teams involved in conceptual data modeling tasks. Additional research in this area would need to clarify what about this particular experiment might have contributed to these results.
- The Effects of Web-Based Learning Versus Traditional Instructor-Based Learning on Student Knowledge and Satisfaction Based on Student Learning Styles
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to compare the effects of Web-based learning (WBL) versus those of traditional instructor-based learning (IBL) on student knowledge and satisfaction based on student learning styles. Other goals were to determine if WBL is more effective for those with a particular learning style. The study examined a sample of undergraduate students who were enrolled in the college algebra offered as both oncampus instructor-based (traditional) and Web-based at the university of North Texas (UNT). A total of 36 Web-based students and 58 instructor-based students participated in this study. This study utilized a posttest-only intact group. The Kolb Learning Style Inventory (LSI) measured the learning styles of students. This study used learning methods (Web-based learning (WBL), instructor-based learning (IBL)), and learning styles (Diverger, Converger, Assimilator, and Accommodator) as independent variables. Student knowledge and student satisfaction was measured at the end of the course as independent variables. Based upon the results of the LSI, post-learning exam, and satisfaction a series of two-way analysis of variance (ANOVA 4x2) techniques and independent variable tests was used for each of the dependent variables, knowledge and satisfaction, based on a student's learning styles. The results revealed that students' learning styles were statistically significant for knowledge when learning on the Web versus instructor-led. In addition, the learning style was important factor for Web-based learning. The results indicated students with Assimilator and Converger as learning styles received better result with the Web-based learning method. Furthermore, this study found there is significant difference in student satisfaction based on learning on the Web versus instructor-led. The outcome of the study could be of particular interest in educational institutions; especially those that want to transfer some of their traditional courses onto the Web. The finding also has implications for training organizations as they seek efficient and effective ways to satisfy their training needs.
- Emotional/behavioral disturbance and speech/language disorders: Prevalence of the dual diagnoses in a school-age population
- The purpose of this study was to examine the prevalence of the comorbidity of emotional/behavioral disorders (EBD) and speech/language disorders among those students identified as under The Individuals With Disabilities Education Act criteria as emotionally disturbed and speech impaired. The literature reviewed included clinical and school settings that examined a cooccurrence of language disorders in the EBD population. Other research reported a lack of routine involvement of speech/language therapists in the assessment of the EBD population. Implications from clinical studies suggested a need for greater attention to language disorders in a multi- and interdisciplinary assessment. This study investigated the prevalence of the dual occurrence of EBD and speech/language disorders in Grades 2 through 6 in Texas schools in light of the known research. Relationships in ethnicity and socioeconomic status were examined using chi-square test of independence. Aggregate data were obtained from the database of the Texas Pupil Information Management System and from survey questionnaire responses provided by speech therapists in selected districts. The literature review focused on the impact of language in the development of appropriate personal interactions and communication skills, especially those relevant to pragmatic language factors and the implications of language competency in successful personal living and career roles and supported the importance of language as an important contributor to a person's life success and the correlation of EBD disabilities and speech/language disorders. Social skills instruction, the relationship of language, especially pragmatics, and social competencies for this population are included. The results revealed a relationship between ethnicity and speech/language disorders among the students identified with EBD. In considering the population of students identified as EBD and language disordered, a significant relationship was found between ethnicity and socioeconomic status. Recommendations include suggestions for future research, assessment procedures, classroom interventions, and data collection methods.
- Enhanced learning performance in the middle school classroom through increased student motivation, by the use of educational software and question-based gaming technology.
- The purpose of this research was to determine if the introduction of a competitive and collaborative computer-based gaming software system into middle school classrooms would result in improved attendance and grades, and motivate students to have a greater interest in their studies. This study was conducted over a 6 week period, with attendance and performance data being collected from 284 students. Two quantitative surveys were used to measure course interest and motivation: (a) the Course Interest Survey (CIS), and (b) the Instructional Materials Motivation Survey (IMMS). Participation in these surveys consisted of 84 students taking the CIS and 40 students taking the IMMS. The results indicated that the experimental group showed statistically better scores than the comparison group in attendance and performance. Students participating in the experimental group had significantly lower mean ranks of absenteeism compared to students in the comparison group. Results also revealed significant differences on grades. Students that were in the experimental group had significantly higher grades compared to students that were in the comparison group. Results of the CIS suggest that a statistically significant difference does not exist on Attention, Relevance, Confidence, and Satisfaction between the experimental and comparison groups. Results of the means and standard deviations for the IMMS Motivation Scores fell somewhere between Moderately true and Mostly true. This research study suggests that student's attendance and performance can be improved when quiz based gaming software that is both collaborative and competitive is used regularly in the classroom. However, for student's that participated in the gaming software, their interest in studying the subject doesn't appear to be significantly different from students that did not participate.
- Enhancing skill maintenance through relapse prevention strategies: a comparison of two models.
- In a quasi-experimental field study, two posttraining interventions composed of relapse prevention (RP) strategies were compared and tested for the effects on participant transfer outcomes. Participant retention of training content, skill maintenance, use of relapse prevention strategies, and self-efficacy served as the dependent variables. Self-efficacy was also tested as a mediator between the experimental treatment levels and both participant skill maintenance and participant use of RP strategies. Participants (n = 39) included managers, directors, and supervisors from various departments within a multi-national telecommunications organization located in a large southern city. After participating in a four-hour leadership development training, two of the three groups participated in a 30-40 minute training where they received one of two RP interventions. One intervention included the steps of (1) identifying potential obstacles to positive training transfer, (2) predicting the first lapse to pretraining behavior, and (3) applying relevant coping strategies to thwart a lapse. The alternative RP intervention included the same steps in addition to a goal setting step. Descriminant descriptive analysis was used to test for group differences across the response variables and to identify on which variables the groups differed. Three separate regression equations were used to test for the mediating relationship of self-efficacy between the RP treatment levels and participant skill maintenance and participant use of RP strategies. Results indicated minimal, but non-statistically significant results between treatment levels and each of the response variables. Self-efficacy was not found to mediate the relationship between RP treatment level and participant skill maintenance or participant use of RP strategies, but did function as a strong predictor of both variables. Suggestions for future research include using additional motivational and efficacy variables to better explore group differences and including efficacy-inducing methods both in training design and as part of a transfer intervention to enhance training transfer. Further, specific suggestions concerning conceptual and psychometric refinement of the RP construct are discussed.
- Equivalency of paper-pencil tests and computer-administered tests.
Access: Use of this item is restricted to the UNT Community.
Are computer-administered versions of a multiple choice paper-pencil test equivalent? This study determined whether there were any significant differences between taking a traditional pencil-paper test and taking the same test using a computer. The literature has shown that there are intervening variables that have caused differences when not controlled. To prove equivalency between test modes, scores have to have similar means, dispersions, and shapes; the ranked-order of the scores must also be similar. Four tests were given over the course of a 16-week semester. The sample was divided, half taking paper-pencil tests and half taking the same test administered by a computer. The mode of administration was switched with each test administration. The analysis showed that, when the intervening variables were controlled, the two modes of administration were equivalent. The analysis used a 2x4 ANOVA, which showed no difference between test modes, but showed that each test administration was significantly different. The Levene statistic was used to test whether dispersions were equivalent and confidence intervals were established to test the kurtosis and skewness statistics. Finally, each of the test scores were transformed into their Normal Curve Equivalents so that Pearson's coefficient could be used to determine the equivalency of the ranked-orders.
- Establishing the utility of a classroom effectiveness index as a teacher accountability system.
- How to identify effective teachers who improve student achievement despite diverse student populations and school contexts is an ongoing discussion in public education. The need to show communities and parents how well teachers and schools improve student learning has led districts and states to seek a fair, equitable and valid measure of student growth using student achievement. This study investigated a two stage hierarchical model for estimating teacher effect on student achievement. This measure was entitled a Classroom Effectiveness Index (CEI). Consistency of this model over time, outlier influences in individual CEIs, variance among CEIs across four years, and correlations of second stage student residuals with first stage student residuals were analyzed. The statistical analysis used four years of student residual data from a state-mandated mathematics assessment (n=7086) and a state-mandated reading assessment (n=7572) aggregated by teacher. The study identified the following results. Four years of district grand slopes and grand intercepts were analyzed to show consistent results over time. Repeated measures analyses of grand slopes and intercepts in mathematics were statistically significant at the .01 level. Repeated measures analyses of grand slopes and intercepts in reading were not statistically significant. The analyses indicated consistent results over time for reading but not for mathematics. Data were analyzed to assess outlier effects. Nineteen statistically significant outliers in 15,378 student residuals were identified. However, the impact on individual teachers was extreme in eight of the 19 cases. Further study is indicated. Subsets of teachers in the same assignment at the same school for four consecutive years and for three consecutive years indicated CEIs were stable over time. There were no statistically significant differences in either mathematics or reading. Correlations between Level One student residuals and HLM residuals were statistically significant in reading and in mathematics. This implied that the second stage of the model was consistent for all students. Much is still unknown concerning teacher effect on student achievement, especially when confined to teacher activity within one school year. However, results indicate the utility of using statistical modeling of student achievement within the context of teacher accountability.
- An evaluation of job satisfaction among salespersons in a small department store using four psychological measures.
- The purpose of this study was to examine the potential of three independent psychological scales (Rotter's Locus of Control, Karasek's Job Content Questionnaire [non-injury job stress], and Rosenberg's Self-Esteem Scale) to predict job satisfaction, as measured by Brayfield and Rothe's Index of Job Satisfaction, among salespersons in a small independent department store in Wichita Falls, Texas. An 82-item survey which examined the dynamics of a salesperson's work life was administered to 20 individuals who were full-time employees of the department store. Demographic data were also gathered although these factors were not entered into the regression analysis. A multiple regression procedure examined the responses of the 20 employees who participated in the study. The R-squared coefficient indicates that 41 percent of the variance in Job Satisfaction was explained by the three predictor measures. A major proportion of this unexplained variance may be in variables outside the scope of this study, e.g., salaries, vacation time, benefits, bonuses, or commissions. Results suggest that the independent variables measured by the Locus of Control Scale and the Job Content Questionnaire in combination were the best predictors of job satisfaction with a significance level of .01. The single best predictor was the Job Content Questionnaire, significant at .03. The three instruments (Locus of Control, Self-Esteem, and Job Content Questionnaire) which comprised the independent variables, reached a significance level of .03 in their prediction of job satisfaction (Brayfield-Rothe Index of Job Satisfaction). Study results indicate that a majority of the employees in the sample population were satisfied with their jobs and with the leadership style manifested by the store manager. In addition, job security was believed to be satisfactory. Inasmuch as there is a void in the literature regarding personal characteristics of salespersons as variables that interact with job satisfaction, comparisons of the findings of this research with other studies that have explored the intricacies of job satisfaction among salespersons who work in small, independent department stores cannot be made. Further research on the predictability of job satisfaction among salespersons in small, independent retail operations such as the department store investigated in this study would be useful not only to managerial staff in decision making and personnel management but would promote greater understanding of the personal characteristics of salespersons as human investment capital which has the potential to create the effective competitive edge required for survival in the new economy.
- An examination of computer anxiety related to achievement on paper-and-pencil and computer-based aircraft maintenance knowledge testing of United States Air Force technical training students.
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to determine whether varying levels of computer anxiety have an effect on computer-based testing of United States Air Force technical training students. The first chapter presents an overview of computer-based testing, defines key terms, and identifies questions addressed in the research. The rationale for conducting this study was that little research had been done in this area. The second chapter contains a review of the pertinent literature related to computer-based testing, computer anxiety, test reliability, validity, and gender differences in computer use. Due to the lack understanding concerning any effects of computer anxiety on computer-based testing, this has been a worthwhile topic to explore, and it makes a significant contribution to the training field. The third chapter describes the qualitative research methodology used to conduct the study. The primary methodology was an analysis of variance comparison for groups of individuals who displayed high or low computer anxiety to their respective mean computer-based or paper-based aircraft maintenance knowledge testing scores. The research population consisted of United States Air Force aircraft maintenance craftsmen students attending training at Sheppard Air Force Base, Texas. The fourth chapter details the findings of the study. The findings indicate that there was no significant difference between the groups of students rated with high computer anxiety and low computer anxiety while testing with computers. Additionally, no significant differences were detected while testing alternative hypotheses covering differences between groups of students rated with high computer anxiety and low computer anxiety testing by traditional paper-and pencil methods. Finally, a reference section identifying the literature used in the preparation of this dissertation is also included.
- An examination of factors related to the cognitive and affective empathy levels of adjudicated youth
- With the advent of increased juvenile delinquency in our nation, the need for prevention and rehabilitation is paramount. Juvenile delinquent acts are becoming more serious and violent with offenders perpetrating at younger ages. Analysis suggests an increase in juvenile crime in the near future (Stone, 2000). Pinpointing the cause of delinquency is an arduous task because of the many contributing factors (e.g., impulsivity, aggression, low intellect, poor family attachment, drug, and alcohol abuse). By changing the emotional deficits found in beginning delinquency, the likelihood of developing delinquent behavior may be impeded. Research indicates that adolescents who commit crimes are lacking in empathy (e.g., Aleksic, 1975; Cohen & Strayer, 1996; Ellis, 1982; Gibbs, 1987; Marcus & Gray, 1998), thus, promoting empathy may be an avenue for prevention and rehabilitation. This study examined the levels of empathy of adjudicated youth in four juvenile correctional facilities in Texas. Using the Interpersonal Reactivity Index (IRI), empathy levels of 170 youth were examined. Youth in the study demonstrated low levels of empathy. The study found that empathy levels of adjudicated youth were differentiated by incarcerating facility, IQ, type of offense, disability status, and phase level of a re-socialization training program. Age was not found to be a significant factor for differentiating empathy levels. Youth demonstrated similiar empathy levels at three of the four incarcerating facilities. However, empathy scores were still below average. IQ ranges were differentiated by the IRI, and found to be lower than normed scores. Type of committing offense was discriminated and found to indicate low empathy levels. Youth without an identified disability scored lower than subjects with emotional/behavioral disorders (E/BD) and youth with learning disabilities (LD). This may reflect the pattern of underidentification of juveniles in correctional facilities (Nelson, Rutherford, & Wolford, 1987). Phases of Re-socialization is an instructional therapuetic program with an empathy component used at the Texas Youth Commission correctional facilities. Data from the study indicated that youth at higher phase levels demonstrated increased empathy. Much of the data are inconsistent, thus establishing the need for further research. A deeper understanding of the impact of each factor (e.g., incarcerating facility, age, IQ, type of offense, disability status, phase) may be accomplished by further research. However, data from this study is consistent with previous research (e.g., Daberman, 1999; Ellis, 1982; Gibbs, 1987; Lee & Prentice, 1988), indicating a link between juvenile delinquents and empathic deficits.
- Examination of Web-based teaching strategies at the University of North Texas.
- This study examined the degree to which University of North Texas (UNT) instructors involved in Web-based instruction are implementing teaching strategies as identified in Chickering and Gamson's (1987) model, seven principles for good practice in undergraduate education. In addition, the study examined training received by instructors in developing and delivering a Web-based course and the relationships between their training and reported use of the teaching strategies in the seven principles. The study also examined the relationship between the number of Web-based courses taught and the use of the teaching strategies. Seventy-two surveys were distributed, with a return rate of 90.3%. Results of the first three research questions were as follows: (a) Self-taught (49%) and UNT Center for Distributed Learning (CDL) (31%) were the most frequently used types of training in preparation for teaching a Web-based course, whereas peer taught (17%) and conferences/workshops (3%) were the least used; (b) the average number of Web-based courses taught by the instructors was M = 8.26; and (c) the most frequently used principles were "Gives prompt feedback" and "Communicates high expectations." UNT CDL assists faculty with the development and delivery of online courses, offering a series of training courses to better prepare faculty to use Web-CT. The relationship between the training received and the instructors' reported use of the teaching strategies was examined using correlations and a MANOVA analysis. The correlations resulted in both positive and negative relationships between the four types of training and three of the principles. The MANOVA procedure found significant differences between self taught instructors and instructors that received most of their training through the CDL in relation to the principle "Respects diverse talents and ways of learning." The final research question examined the relationship between the number of courses taught and instructors' reported use of the teaching strategies, revealing that a positive correlation existed between the number of courses taught and four of the seven principles.
- Exploring the relationship between continuing professional education and job satisfaction for information technology professionals in higher education.
- The study had four main hypotheses that examined the relationships between job satisfaction and the reasons for attending continuing professional education (CPE). The purpose of this study was to examine the relationships between training and job satisfaction with the objective of adding to the body of knowledge related to both job satisfaction and training and development. Participation Reasons Scale was used to measure the reasons for attending CPE activities, and the Job in General Scale and Job Descriptive Index was used to measure job satisfaction. The surveys were administered over the Internet to information technology professionals working in higher education. The participants were contacted by email with a message explaining the purpose of the research and a Web link that took the participants directly to the survey. After collecting the data, it was exported into SPSS and analyzed using Spearman Rho and Mann Whitney U statistics and a simple structure exploratory factor to determine any underlying structures between the job satisfaction and CPE.
- Faculty training and professional development programs designed to impact Web-based instruction in higher education: A faculty perspective.
- Web-based instruction has fast become a common component of higher education. Although such instruction began as a supplemental form of interaction, it has now become a basic aspect of many college courses and degree programs. If teacher and student are not in the same place at the same time, it becomes necessary to introduce a communications medium that will not only deliver information but also provide a channel of interaction between them. This study focused on faculty training and development programs designed to impact Web-based instruction in higher education at the five largest state-funded universities in Texas within a college of education. The instrument used in this study was developed by the research to collect data relating to faculty perception of training and development opportunities available to them at their institutions, perceptions of administrative support, and technical support. The objective was to determine if there was a relationship between these items listed above and faculty members' levels of confidence and perceptions of effectiveness when teach Web-based courses. The population consisted on 151 faculty members at the University of Texas at Austin, Texas A&M University, the University of Houston, the University of North Texas, and Texas Tech University. This research study suggests that full-time tenure track faculty members at the five largest state-funded universities in Texas perceive that the amount of formal training they have received increases their ability to teach Web-based courses effectively and that the amount of formal training received also increases their perceived level of confidence when teaching Web-based courses. The researcher discovered similar results when faculty members were asked about their perceived level of institutional commitment and current initiatives for teaching Web-based courses.
- Female adolescents identified with emotional disturbance and adjudicated female adolescents: A comparison of self-concepts.
- This study addresses the academic, social, and self-image self-concepts of females ages 13-17 who are labeled emotionally and behaviorally disordered by their public school systems and are in residential treatment, and females ages 13-17 who are adjudicated, or labeled “juvenile offenders” and are involved with the juvenile justice system. The purpose of this study is to examine and compare the self-concepts of these populations of adolescent females. Research questions focus on whether or not there is a difference in the confidence scores of self-image, academic, and social self-concepts, the importance scores of self-image, academic, and social self-concepts, and the confidence composite and outcome composite scores among female adolescents according to whether or not the female is adjudicated. Results show no statistically significant differences on seven of the eight measures. On the eighth measure, a statistically significant difference was found, with the non-offenders having a higher Outcome Confidence Composite score than the offenders.
- First-term Air Force medical service corps officers: Relationship between MBTI® and initial occupational placement to predict job satisfaction.
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to determine whether a relationship exists between the Myers-Briggs Type Indicator® (MBTI®) of first-term Air Force medical service corps (MSC) officers and their initial occupational placement matches (OCUPLACE MATCH), and, if so, whether this could it predict job satisfaction. The population consisted of 116 first-term Air Force MSC officers already assigned and working at their initial occupational placement. Statistical Package for the Social Sciences (SPSS®) computer software program was used for the statistical computation. Several techniques were used, including, frequency distribution, the Pearson product-moment correlation coefficient, and regression analyses, among others. Results showed a statistical significant correlation between the MBTI type of the first-term MSC officer matches and their initial occupational placement (OCUPLACE MATCH, r = .440, p < .01). Furthermore, results of a regression analysis showed no statistical significance for predication on job satisfaction (r = 492, F = .887, p < .05). Based on this study, the Air Force Personnel Center can match first-term MSC officers' personality type to an initial occupation placement; however, based on the second part of the hypothesis, prediction of job satisfaction may not be yield on less other aspects of the group are considered such as time in service, source of recruitment, initial occupation's location, etc.
- Hiring preferences of employers of entry-level biomedical equipment technicians in Texas.
- This study examined the signaling strength, or marketing power, of the most common qualifications of entry-level biomedical equipment technicians (BMETs) in Texas, based on stated hiring preferences of BMET managers, using order ranking of fictitious resumes. This study also sought to determine whether certification status, education background, military training background as a BMET, or type of employer [hospital or ISO] of the hiring manager had an effect on hiring preference for applicant qualifications of associate degree, military training as a BMET, or certified biomedical equipment technician (CBET) certification candidacy. Participants were asked to rank 16 fictitious resumes representing the most common qualifications of entry-level BMETs and to fill out a background questionnaire regarding their education, military, certification, and employer. The number of times each resume ranked in first place was tabulated and inter-rater reliability was calculated. Resumes with qualifications of associate degree versus military training as a BMET were compared at three levels of work experience. A chi-square test for independence was conducted for the comparisons to determine whether work experience influenced preference. Chi-square tests were also conducted for comparisons of associate degree with candidacy for CBET certification versus associate degree and military training with CBET candidacy versus military training. No statistically significant results were found for the chi-square tests, indicating that work experience did not significantly influence participant preferences for the compared qualifications. BMET hiring managers indicated a preference for combinations of qualifications rather than any single qualification. Correlations in hiring managers' educational background, certification status, military training as a BMET, type of employer, and preference for applicant qualifications were examined. Statistically significant correlations were found between participants' preference for associate degree or military training and level of education, military training background, and type of employer. Statistically significant correlations were also found between participants' preference of military training with CBET candidacy over military training alone and military training as a BMET background as well as certification background.
- The historical significance of professional contributions of a leader in the field of emotional and behavioral disorders in special education: A qualitative case study of Richard J. Whelan.
- Historical documentation of the impact of PL 88-164 on the field of emotional and behavioral disorders (E/BD) and the development and implementation of teacher-training programs for children and youth identified as E/BD is limited. This study was designed to document the historical significance and professional contributions of Dr. Richard J. Whelan, Professor Emeritus, University of Kansas and his work in the development of teacher preparation training programs in the field of E/BD in institutions of higher education (IHE). The second purpose of this study was to document the legislative and program initiatives that have impacted the services, education, teaching, and research initiatives in the field of E/BD as interpreted by Dr. Whelan. The final purpose of this study was to examine the views of Dr. Whelan regarding the need for future developments in the field of E/BD. Legislative and policy efforts continue to change the climate in which children are educated. The field of special education relies on the efficacy of the training programs in IHE to provide appropriate teaching and research efforts in a manner that is consistent with the current needs of students with E/BD, their families, and the schools in which they seek to be educated. As this study revealed, understanding the history of the field, the foundational framework from which research and evidence-based practices have emerged, is paramount to forward movement in the field and necessary to the measurement of effective interventions and strategies in support of the students, their families, and those who choose this field as their lifework. It is the foundation from which educational theory is developed, researched, revised, and reflected.
- The impact of technical barriers on the effectiveness of professional development as related to a distance education system-based course: A case study in the Web World Wonders environmental science learning community.
- This study reports and discusses the impact of technical barriers on the effectiveness of professional development as related to a distance education system based course: a case study of the web world wonders environmental science learning community in Florida. The project involved 4th through 12th grade public school teachers learning how to use GPS readers, digital cameras, and Arc View software for the purpose of utilizing a Website that enabled remote Internet camera access in Florida State Parks. Under the supervision of Florida State University and the Florida Department of Education those teachers received professional development in techniques for developing lesson plans utilizing the equipment and software as stated above. Using the Concept Based Adoption Model, a description of the teacher's demographics, Levels of Use and Stages of Concern with relation to gender, age, teaching experience, and technological experience was examined. Technical barriers were identified and an explanation of how they were overcome in the process of receiving the professional development is reported.

- Intent to quit perceptions of nursing assistants working in Oklahoma state veterans administration-owned and administered nursing homes.
- The purpose of this study was to examine a select set of organizational variables and determine their relationship to nursing assistants' intentions to quit in state-owned veterans' long-term care facilities located across the United States. America's long-term care industry (e.g., nursing homes, assisted living facilities) is a multibillion dollar industry. Because the U.S. government is projecting a 250% increase in the elderly population, staffing these nursing homes and related facilities is a critical concern. A vitally important but often overlooked factor of the long-term care industry is employee turnover. Of the staff in long-term care facilities, the nursing assistant (NA) position is particularly susceptible to turnover. Approximately 80% of NAs who enter the workforce leave within the 1st year and many leave within the first 3 months of employment. Some facilities report that they are unable to accept new residents because of a lack of qualified NAs. While many studies have researched this issue, staff turnover in long-term care facilities remains a serious and widespread problem. This study provides a foundation for future research related to the perceptions of intentions to quit of nursing assistants (NAs) working in state-owned veterans long-term care facilities by providing primary data regarding NAs intentions to quit. Results of this study indicate that NA intentions to quit might be reduced provided that pay and rewards are increased, workplace violence is addressed, and better access to patient care plans is provided. This research is useful to state-owned and operated long-term care facilities by giving them additional insights into nursing assistants' intentions to quit perhaps resulting in lower rates of turnover. It is suggested that future research be performed using populations of individuals from other segments of the long-term care industry, mainly, for-profit institutional care nursing homes, and federally owned veterans long-term care facilities.
- An Investigation into Motivations of Instructors Teaching Business and Technical Internet-Based Courses at Two-Year Colleges
- This research was conducted to determine why two-year community college instructors teach over the Internet. By understanding why these instructors teach over the Internet, colleges can recruit more instructors to teach using the Web thus allowing colleges to offer more Internet courses. They can also use the information to keep the instructors who are currently teaching over the Internet satisfied, and motivate them to continue to teach. To gather this information, a questionnaire was created and evaluated for reliability and validity during a pilot study. It was then sent to those instructors who taught over the Internet, and had their e-mails available on their campus Website. A 30.5% response rate (N=100) was achieved. The survey was divided into two sections, a demographics section and a Likert scale dealing with motivation. The Likert scale had six choices ranging from strongly agree to strongly disagree and 31 statements. The demographic data were reported and summarized. The Likert items were examined using factor analysis techniques, and a number of components were discovered. Eight components, made up of the 31 variables from the Likert scale were found using the factor analysis. The eight components in order are labeled: Technical and Computer Challenges, School Promotion, Student Preferences, Personal Benefits, Receiving Computerized Assistance, Growth and Knowledge, Textbook Company Assistance, and Pay.
