An Investigation of Factors Affecting Test Equating in Latent Trait Theory

An Investigation of Factors Affecting Test Equating in Latent Trait Theory

Date: August 1998
Creator: Suanthong, Surintorn
Description: The study investigated five factors which can affect the equating of scores from two tests onto a common score scale. The five factors studied were: (a) distribution type (i.e., normal versus uniform); (b) standard deviation of itemdifficulties (i.e., .68, .95, .99); (c) test length or number of test items (i.e., 50,100, 200); (d) number of common items (i.e., 10,20,30); and (e) sample size (i.e., 100, 300, 500). The significant two-way interaction effects were for common item length and test length, standard deviation of item difficulties and distribution type, and standard deviation of item difficulties and sample size.

The Effect of Time on Training Retention Rates of United States Air Force Loadmaster Apprentice Students

The Effect of Time on Training Retention Rates of United States Air Force Loadmaster Apprentice Students

Date: December 1998
Creator: Canada, Angela F. (Angela Faye)
Description: The purpose of this study was to determine if extended periods of time out of the training environment has an effect on the retention of training. The rationale for conducting this study was based on the fact that little research has been done in this area. The findings of the study indicated that extensive periods of time out of training do significantly influence the amount of training retained fromone loadmaster course to the other. Additionally, there was a significant relationship between the number of days out of training and the posttest scores. The optimum training break between courses appears to be between 10 and 20 days. Training retention is apparently affected by time.

Endogenous Constructivist Implications for Methodology : Focus on Young Children with Developmental Delay in the Social and Emotional Domains

Endogenous Constructivist Implications for Methodology : Focus on Young Children with Developmental Delay in the Social and Emotional Domains

Date: December 1998
Creator: McCrary, Donna E. (Donna Evelyn)
Description: The Ecologically-Based Activity Plan (EBAP) is proposed as a method to create a transition between special education and general education. It serves as a tool to help classroom teachers assess the environment of the class and as a method for embedding instruction within the naturally occurring context of the endogenous constructivist classroom. In this study the EBAP was used to reduce aggressive behavior and increase prosocial behavior among five children who displayed developmental delays in the social and emotional domains.

Problem-Based Learning for Training Teachers of Students with Behavioral Disorders in Hong Kong

Problem-Based Learning for Training Teachers of Students with Behavioral Disorders in Hong Kong

Date: August 1999
Creator: Heung, Vivian Woon King
Description: This study attempts to explore the perceived value of Problem-Based Learning (PBL) in training teachers of students with behavioral disorders (E/BD) in Hong Kong. It represents an effort to improve the predominately lecture focussed approach adopted in many preparation programs. Data on the training needs of Hong Kong teachers were also acquired and 31 knowledge/skills areas related to teaching students with E/BD were identified. Subjects viewed the PBL approach as dynamic, interesting and incentive driven. It develops skills involved in group learning, self-directed learning, use of information resources and problem-solving. Most important, teachers felt they were supported to explore the practical problems they personally encountered in the classroom and actions they could take to resolve them. Difficulties in using PBL included a lack of resources and the tendencies of most Chinese students to accept rather than challenge others' ideas.

The Relationship Between Time-On-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College

The Relationship Between Time-On-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College

Date: December 1999
Creator: Lansford, Carl Edwin
Description: This research sought to determine what relationship exists between time-on-task in computer-aided instruction (CAI) using Destinations courseware and progress in reading ability of developmental reading students as indicated by the reading portion of the Texas Academic Skills Program (TASP) test. Time-on-task is the time during which a student actively works on Destinations activities, as recorded by the software management system. TASP, an exam required of all students in Texas public colleges, assesses reading, math, and writing skills. The population was made up of 482 students who took the TASP exam before and after CAI and who used Destinations CAI for remediation of reading skills. Null hypotheses were explored using Pearson correlation and linear multiple regression. The findings for the null hypotheses were the following: Ho1 - Correlation and linear regression correlation showed that time-on-task in Destinations CAI had no significant effect on the TASP scores of the population studied. Ho2 - Correlation and linear regression correlation showed that females made significantly better gains on the TASP test from CAI than males. Ho3 - Correlation and linear regression correlation showed that low-achiever students made no better gains on the TASP test from time-on-task in CAI than high-achiever students. Difference between the ...

Effects of a Simulation Game on Trainees' Knowledge and Attitudes About Age-related Changes in Learning and Work Behaviors of Older Workers

Effects of a Simulation Game on Trainees' Knowledge and Attitudes About Age-related Changes in Learning and Work Behaviors of Older Workers

Date: May 2000
Creator: Dunn, Suzanne
Description: 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 ...

Emotional/Behavioral Disturbance and Speech/Language Disorders: Prevalence of the Dual Diagnoses in a School-Age Population

Emotional/Behavioral Disturbance and Speech/Language Disorders: Prevalence of the Dual Diagnoses in a School-Age Population

Date: May 2000
Creator: Silver, Kathi Olinsky
Description: 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 ...

An Online Academic Support Model for Students Enrolled in Internet-Based Classes

An Online Academic Support Model for Students Enrolled in Internet-Based Classes

Access: Use of this item is restricted to the UNT Community.
Date: May 2000
Creator: Rockefeller, Debra J.
Description: This doctoral dissertation describes a research study that examined the effectiveness of an experimental Supplemental Instruction (SI) program that utilized computer-mediated communication (CMC) rather than traditional SI review sessions. During the Spring 1999 semester, six sections of an introductory computer course were offered via the Internet by a suburban community college district in Texas. Using Campbell and Stanley's Nonequivalent Control Group model, the online SI program was randomly assigned to four of the course sections with the two remaining sections serving as the control group. The students hired to lead the online review sessions participated in the traditional SI training programs at their colleges, and received training conducted by the researcher related to their roles as online discussion moderators. Following recommendations from Congos and Schoeps, the internal validity of the groups was confirmed by conducting independent t-tests comparing the students' cumulative credit hours, grade point averages, college entrance test scores, and first exam scores. The study's four null hypotheses were tested using multiple linear regression equations with alpha levels set at .01. Results indicated that the SI participants earned better course grades even though they had acquired fewer academic credits and had, on average, scored lower on their first course ...

Prediction of Community College Students' Success in Developmental Math with Traditional Classroom, Computer-Based On-Campus and Computer-Based at a Distance Instruction Using Locus of Control, Math Anxiety and Learning Style

Date: May 2000
Creator: Blackner, Deborah Martin
Description: The purpose of this study was to investigate the relationship between individual student differences and academic success in three pedagogical methods (traditional classroom, computer-aided instruction (CAI) in an on-campus setting, and CAI in a distance education setting) for developmental mathematics classes at the community college level. Locus of control, math anxiety and learning style were the individual differences examined. Final grade, final exam score and persistence were the indicators of success. The literature review focused on developmental mathematics, pedagogical techniques and variables contributing to academic performance. Two parallel research populations consisted of 135 Beginning Algebra students and 113 Intermediate Algebra students. The Rotter I-E Locus of Control Scale, the Abbreviated Mathematics Anxiety Rating Scale, the 4MAT Learning Type Measure, and an instrument to gather demographic data were used. It was the conclusion of this study that the instructional methods were not equal with respect to achievement. In Beginning Algebra, the CAI students received significantly higher final grades than did the traditionally taught students. In Intermediate Algebra traditional students scored significantly higher on the final exam than did the CBI students. There were more students persisting than expected in traditionally taught Beginning Algebra and no significant difference in attrition in Intermediate ...

Comparison of Computer Testing versus Traditional Paper and Pencil Testing

Comparison of Computer Testing versus Traditional Paper and Pencil Testing

Date: August 2000
Creator: Millsap, Claudette M.
Description: 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.

An Examination of Factors Related to the Cognitive and Affective Empathy Levels of Adjudicated Youth

An Examination of Factors Related to the Cognitive and Affective Empathy Levels of Adjudicated Youth

Date: August 2000
Creator: Broom, Ellen Wildemann
Description: 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 ...

Students' Criteria for Course Selection: Towards a Metadata Standard for Distributed Higher Education

Students' Criteria for Course Selection: Towards a Metadata Standard for Distributed Higher Education

Date: August 2000
Creator: Murray, Kathleen R.
Description: By 2007, one half of higher education students are expected to enroll in distributed learning courses. Higher education institutions need to attract students searching the Internet for courses and need to provide students with enough information to select courses. Internet resource discovery tools are readily available, however, users have difficulty selecting relevant resources. In part this is due to the lack of a standard for representation of Internet resources. An emerging solution is metadata. In the educational domain, the IEEE Learning Technology Standards Committee (LTSC) has specified a Learning Object Metadata (LOM) standard. This exploratory study (a) determined criteria students think are important for selecting higher education courses, (b) discovered relationships between these criteria and students' demographic characteristics, educational status, and Internet experience, and (c) evaluated these criteria vis-à-vis the IEEE LTSC LOM standard. Web-based questionnaires (N=209) measured (a) the criteria students think are important in the selection of higher education courses and (b) three factors that might influence students' selections. Respondents were principally female (66%), employed full time (57%), and located in the U.S. (89%). The chi square goodness-of-fit test determined 40 criteria students think are important and exploratory factor analysis determined five common factors among the top 21 ...

Psychometric Development of the Adaptive Leadership Competency Profile

Psychometric Development of the Adaptive Leadership Competency Profile

Date: December 2000
Creator: Sherron, Charles T.
Description: This study documented the psychometric development of the Adaptive Leadership Competency Profile (ALCP). The ALCP was derived from a qualitative database from the National Science Foundation project (NSF 9422368) and the academic body of literature. Test items were operationalized, and subject matter experts validated 11 macro-leadership competencies and 65 items. Rasch rating scale measurement models were applied to answer the following questions: (a) How well do the respective items of the ALCP fit the Rasch rating scale measurement model for the 11 scales of the ACLP? (b) How well do the person's abilities fit the Rasch rating scale measurement model, using the 11 scales of the ALCP? (c) What are the item separation and reliability coefficients for the 11 ALCP scales? (d) What are the person separation and reliability coefficients for the 11 ALCP scales? This study also sought to discern whether the ALCP could predict leader effectiveness as measured by the likelihood ratio index and frequency of correct predictions indices. The WINSTEPS and LIMDEP programs were used to obtain Rasch calibrations and probit estimates, respectively. The ALCP profiles the frequency and intensity of leadership behavior. Composite measures were calculated and used to predict leadership effectiveness. Results from this study ...

The Effect of Psychological Type, Economic Status, and Minority

The Effect of Psychological Type, Economic Status, and Minority

Date: May 2001
Creator: Kays, Brenda S.
Description: 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 ...

Equivalency of paper-pencil tests and computer-administered tests.

Equivalency of paper-pencil tests and computer-administered tests.

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Whitworth, Clifford K.
Description: 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 ...

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.

Date: December 2001
Creator: Teaff, Teresa L.
Description: 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 ...
