The problem in this study was to determine the relationship between the scores on the three parts (reading, writing, and mathematics) of the Texas Assessment of Academic Skills Test (TAAS) and the academic success of first-year students at Clarendon College, Clarendon, Texas. High school grade-point average and gender were also included in the study. The purpose of the study was to develop an equation to predict first-year college grade-point average at Clarendon College . The predictor variables were the three parts of the TAAS Test (reading, writing, and mathematics) , high school grade-point average, and gender. The equation was developed through multiple correlation/multiple regression multivariate procedures. All statistical analyses were calculated through sub-programs of the Statistical Package for the Social Sciences (SPSS). The study was limited to using only 1992/1993 Texas high school graduates who had entered Clarendon College in the fall semesters of 1992 and 1993 directly following high school graduation. A search of Clarendon College records produced 115 students from these groups who fully met all standards defined for the study. Two predictor equations were developed. One developed through a simple regression command included all five predictor variables. The second equation was produced through a stepwise procedure. This equation included only high school grade-point average and the mathematics score from the TAAS Test. The variables TAAS reading, TAAS writing, and gender were not found to be significant when used in conjunction with the other predictor variables. The strength of each predictor variable was evaluated using students from the freshman class of 1994-95 at Clarendon College. Each of these students met the same basic standards used to establish the prediction equations. The two prediction equations were found to be equal in predictive strength. There was less than one percent difference in the variance accounted for between the two equations. …
Some researchers are saying that natural language is probably one of the most promising interfaces for use in the long term for simplicity of learning. If this is true, then it follows that speech recognition would be ideal as the interface for computer-based training (CBT). While many speech recognition applications are being used as a means for a computer interface, these are usually confined to controlling the computer or causing the computer to control other devices. The user input or interface has been the recipient of a strong effort to improve the quality of the communication between man and machine and is proposed to be a dominant factor in determining user productivity, performance, and satisfaction. However, other researchers note that full natural interfaces with computers are still a long way from being the state-of-the art with technology. The focus of this study was to determine if the technology of speech recognition is an effective interface for an academic lesson presented via CBT. How does one determine if learning has been affected and how is this measured? Previous research has attempted quantify a learning effect when using a variety of interfaces. This dissertation summarizes previous studies using other interfaces and those using speech recognition. It attempted to apply a framework used to measure learning effectiveness in some of these studies to quantify the measurement of learning when speech recognition is used as the sole interface. The focus of the study was on cognitive processing which affects short-term memory and in-turn, the effect on original learning (OL). The methods and procedures applied in an experimental study were presented.
This study examined the policy letters and verbal testimony transcripts submitted by interest groups to the United States Department of Education (USDE) in response to the proposed regulations pertaining to the implementation of the 1997 reauthorization of P. L. 105-17, Individuals with Disabilities Education Act (IDEA). Specifically, this study analyzed the emerging themes in the area of discipline. Responses were received from the following interest groups: (a) school administrators, (b) parents, (c) teachers, (d) state educational agencies (SEAs), (e) national educational organizations, and (f) members of the United States Congress. In addition to analyzing the emerging themes, the study compared these themes to ones found in the current literature and court cases.
The purpose of this study was to investigate the effects of four learning styles (accommodator, assimilator, converger, and diverger) and two different presentation methods (traditional and computer-based) on knowledge acquisition in a university classroom.
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 purpose of this study was to identify perceived barriers to the implementation of site-based management for administrators in the Region XII Service Center area in Texas.
This study investigated whether a computer-administered mathematics test can provide equivalent results for normal and mathematically disabled students while retaining similar psychometric characteristics of an equivalent paper and pencil version of the test. The overall purpose of the study was twofold. First, the viability of using computer administered assessment with elementary school children was examined. Second, by investigating items on the computer administered mathematics test for potential bias between normally achieving and mathematically disabled populations, it was possible to determine whether certain mathematical concepts consistently distinguish between the two ability groups.
Over the past three to four decades the community college has experienced some tremendous periods of growth and success. Much of this has been due to a growing economy and a growing population. However, the future of the community college may be in for some changes. The effects these changes are having can mean opportunity or disaster depending on the readiness of the institution. The change occurring today requires future insight, swifter action, and a proactive response. Community colleges cannot afford to leave planning for crisis situations. A proactive stance must be taken and tough questions must be asked. In 1991 the Seventy-second Texas Legislature tasked the Legislative Budget Board of Texas with the assignment of developing a long-range strategic plan for state government based on individual agency plans. The passing of House Bill No. 2009 required that all agencies of Texas State Government, including community colleges, develop a strategic plan. The purpose of this study was to determine the significance of certain independent variables towards the perceived importance of three dependent variables - statements of purpose, statements of direction and statements of impact - found in the Legislative Budget Board Strategic Planning Template. Research shows that there are a number of planning paradigms which contain some form of strategic planning. Independent variables such as administrative levels of involvement, levels of experience, levels of strategic planning training, and college location could all be significant factors in determining the success of strategic planning. The results of this study may provide community colleges in Texas with information for better understanding characteristics influencing strategic planning, for identifying strategic planning program barriers, and for evaluating strategic planning program models and outcomes throughout the state.
This study identified the expected knowledge/skills needed for working with children and youth with emotional/behavioral disorders (E/BD) in general education classroom settings, as identified by general educators.
Aircraft maintenance training programs in the Air Force have evolved from an almost exclusively mechanical orientation to one that is largely electronic. The Armed Services Vocational Aptitude Battery (ASVAB) with its four selector composites (Mechanical, Administration, General, and Electronic) has been in use for over 20 years. The mechanical (M) composite score is used to identify those who will be trained in aircraft maintenance.
The purpose of this study was to determine the effectiveness of career group counseling in raising the self-concept of at-risk high school students. The following subgroups were represented in the sample: male and female students, white and non-white ethnic groups, and students from sophomore, junior, and senior classifications. Two groups of students in the Lewisville Independent School District meeting the criteria for at-risk as defined by House Bill 1010 were administered a pretest and posttest using the Piers-Harris Children's Self-Concept Scale. The experimental group was from the Lewisville Learning Center. The control group was students enrolled in the Coordinated Vocational Academic Education (CVAE) classes at Lewisville High School. A treatment sample of 25 students received career group counseling. A nontreatment sample of 25 students did not receive any group counseling. The t-test for independent samples was used to analyze the data. The pretests for the experimental and control groups showed no significant difference at the .05 level. The treatment sample received 30 hours of group counseling in the Fall semester of 1994. At the end of 30 hours of counseling a posttest was administered to the treatment sample and to the control sample. The t-test for independent samples was used to analyze the data. While career group counseling appeared to impact the students in the experimental group, the limitations of sample size and population may have effected the results. The treatment was significant at the .05 level and the null hypothesis was rejected. The findings showed that career group counseling was not an effective tool for increasing positive self-concept. It is concluded that self-concept was not effectively enhanced through group interaction conducted by the school system in this study. Further research is recommended.
This study examined the correlation between two commercially available behavior rating scales. The two scales used were the Behavior Dimensions Rating Scale (BDRS) and the Behavior Assessment System for Children (BASC). Students from a special education behavior management class (primarily students with emotional disabilities) were rated on the two scales and students from a general education behavior management class (primarily students with conduct problems without disabilities) were rated on the two scales.
This study centered on competencies needed by entry-level automotive technicians. Many students in automotive technician programs immediately seek employment upon program completion. This study is one step toward identifying areas in the automotive technician curriculum that need the most training emphasis.
Under investigation in this study was the effect of ASE certification of automotive technician training programs and other selected factors on ASE test outcome and job placement rate. This research ponders whether the time and money invested in certifying technician training programs is returning desired improvements in this automobile manufacturer's dealer service staff. The study focussed on technicians employed at Chrysler dealerships around the United States. The 2 samples totalling 387 males between the ages of 22 and 30 were drawn from 1,007 graduates of automotive technician training programs. Technicians that completed a formal training program beyond the high school level certified by the National Institute for Automotive Service Excellence (ASE) were compared to others whose training was not certified by ASE. Comparisons were made on the basis of ASE Automobile Technician Test scores and on the length of time from training program completion to employment. This research sought to identify the significance of association between three main predictors - the status of training program ASE certification, work experience and year of training program completion - and the most desirable levels of ASE test outcome (at or above 90% on the ASE test) and job placement rate (immediately following completion of training). The logistic regression procedure in SAS was used to analyze categorical data in testing the statistical hypotheses. Resulting odds ratios provided indications of significant associations between ASE program certification, technician experience and year of program completion and each of the dependent variables, ASE test outcome and job placement rate. The findings indicated that ASE automotive training program certification status was a significant predictor of ASE test outcome and of job placement rate. Recommendations for further study suggest a look at how technician skill levels affect implementation of the Clean Air Act or dependency on foreign sources of fuel, …
The need for a high-quality workforce to meet increased competition in the world economy has increased the need for competent vocational administrators in public 2-year postsecondary institutions. Researchers have agreed that vocational education is in a state of metamorphosis and must change to meet its challenges in the coming century. At the same time, more women are seeking and obtaining vocational administrative positions. Several studies have been done to identify the competencies needed by vocational administrators to perform their duties, but there has been little research on the actual ability to perform the administrative tasks identified by these studies. Two main purposes of this study are: (a) to determine the perceived level of administrative competencies possessed by women administrators in vocational education at the community college level in Texas; (b) to determine the adequacy of the preservice training received by these administrators to perform their administrative functions. Of the 175 women administrators randomly selected to participate in the study, 71% completed the Administrator Task Inventory. In addition to the descriptive statistics, two multiple regression analyses were tested. First, principal component analysis was used to reduce the number of dependent variables from 11 to 2, after which two multiple regression analyses were used to test the relationship between the two component scores identified as management-skills factors and educational-skills factors and the four independent variables of level of education, number of years of teaching vocational subject, number of years of vocational administrative experience, and level of vocational professional organization involvement. The results indicate that the women administrators possess the competencies needed to perform their tasks, but one fourth of the administrators need better preservice and/or inservice training on at least 7 of 11 competency categories studied. The results also show that a negative relationship exists between the number of years of teaching …
In a rapidly changing environment of growing competition for limited resources and ever increasing operational costs, institutions of higher education must focus on all aspects of the organizational functions to insure institutional effectiveness and the maximization of student success. This study will use a Student Environment Model (SEM) to assess students' perception of their college environment outside of the formal classroom at a unique two year technical college. The information obtained is used by the administration of Texas State Technical College Waco (TSTCW) to make appropriate adjustments in programs, services, or policies when the student data indicates that change or improvement is needed. While the SEM provides an indication of the students' "image" of the college environment, it can also provide indicators of areas which need improvement or require change. Applying the SEM information to decision making, problem solving, and planning will allow the institution and its people to move toward higher productivity and continuous quality improvement.
Two procedures for detection of differential item functioning (DIF) for polytomous items were generalized to detection of differential testlet functioning (DTLF). The methods compared were the logistic discriminant function analysis procedure for uniform and non-uniform DTLF (LDFA-U and LDFA-N), and the Mantel score test procedure. Further analysis included comparison of results of DTLF analysis using the Mantel procedure with DIF analysis of individual testlet items using the Mantel-Haenszel (MH) procedure. Over 600 chi-squares were analyzed and compared for rejection of null hypotheses. Samples of 500, 1,000, and 2,000 were drawn by gender subgroups from the NELS:88 data set, which contains demographic and test data from over 25,000 eighth graders. Three types of testlets (totalling 29) from the NELS:88 test were analyzed for DTLF. The first type, the common passage testlet, followed the conventional testlet definition: items grouped together by a common reading passage, figure, or graph. The other two types were based upon common content and common process. as outlined in the NELS test specification.
There are several conditions for applying equal weights as an alternative to least squares weights. Psychometric parallelism, one of the conditions, has been suggested as a necessary and sufficient condition for equal-weights aggregation. The purpose of this study is to investigate the effect of psychometric parallelism among predictors on the efficiency of equal weights and least squares weights. Target correlation matrices with 10,000 cases were simulated so that the matrices had varying degrees of psychometric parallelism. Five hundred samples with six ratios of observation to predictor = 5/1, 10/1, 20/1, 30/1, 40/1, and 50/1 were drawn from each population. The efficiency is interpreted as the accuracy and the predictive power estimated by the weighting methods. The accuracy is defined by the deviation between the population R² and the sample R² . The predictive power is referred to as the population cross-validated R² and the population mean square error of prediction. The findings indicate there is no statistically significant relationship between the level of psychometric parallelism and the accuracy of least squares weights. In contrast, the correlation between the level of psychometric parallelism and the accuracy of equal weights is significantly negative. Under different conditions, the minimum p value of χ² for testing psychometric parallelism among predictors is also different in order to prove equal weights more powerful than least squares weights. The higher the number of predictors is, the higher the minimum p value. The higher the ratio of observation to predictor is, the higher the minimum p value. The higher the magnitude of intercorrelations among predictors is, the lower the minimum p value. This study demonstrates that the most frequently used levels of significance, 0.05 and 0.01, are no longer the only p values for testing the null hypotheses of psychometric parallelism among predictors when replacing least squares weights …
This study investigated the problem that educators have throughout the state of Texas. The problem educators have is that reading scores continue to fall short of state expectations. This study investigated the effectiveness of 90 minutes of class time given for reading to students who use the Electronic Bookshelf Program and the effectiveness of the Electronic Bookshelf Program, which is being sold to school districts throughout the nation. The literature review focused on the effectiveness of independent reading on reading achievement, and the effectiveness of using computer-based reading programs to increase reading achievement.
This study examined differences in retention, graduation, and dropout between students in grades 9-12 in special education and regular education in the state of Texas for school years 1992-93 through 1995-96. The purpose was to gather information regarding the possible adverse effects of increased academic standards and mandatory testing on students with disabilities. The results indicate that when compared to students in regular education, students with disabilities are significantly more likely to be retained and are not experiencing the same decline in dropout rates as regular students. There is no indication that students with disabilities have been adversely affected by school reform but the size of the school district may play a significant role in whether or not students with disabilities dropout of school.
This study examined the perceptions of school superintendents of districts and building principals of schools within selected shared service arrangements in the state of Texas who receive services from the cooperative, and selected directors of rural shared service arrangements pertaining to the responsibilities and roles of shared service arrangements when site-based decision-making (SBDM) was used as the guiding philosophy.
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.
The effects of random guessing as a measurement disturbance on Rasch fit statistics (unweighted total, weighted total, and unweighted ability between) and the Logit Residual Index (LRI) were examined through simulated data sets of varying sample sizes, test lengths, and distribution types. Three test lengths (25, 50, and 100), three sample sizes (25, 50, and 100), two item difficulty distributions (normal and uniform), and three levels of guessing (no guessing (0%), 25%, and 50%) were used in the simulations, resulting in 54 experimental conditions. The mean logit person ability for each experiment was +1. Each experimental condition was simulated once in an effort to approximate what could happen on the single administration of a four option per item multiple choice test to a group of relatively high ability persons. Previous research has shown that varying item and person parameters have no effect on Rasch fit statistics. Consequently, these parameters were used in the present study to establish realistic test conditions, but were not interpreted as effect factors in determining the results of this study.
The purpose of this study is to determine the impact on student use of electronic information systems when teachers have been given instruction on their use. By providing teachers with a solid introduction to the technology, a handy reference book, and an easy-to-use evaluation tool, it is expected that they will incorporate information found on the internet into their lessons at least twice a month. In addition, teachers will allow students to access information on their own, provided computers and Internet access are available, at least once a month.
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 two group's gains was not statistically significant. Ho4 - The regression equations predicted the gain in TASP reading scores for less than 1% of the population studied. Only the regression equations for male students and female students separately were statistically significant. The researcher recommends replication of this study each semester to determine the effectiveness of CAI. Regular and systematic evaluation using pretest and posttest data will provide benchmarks so that the value of changes in instructional methods can be measured. This method of research can help to clarify questions that should be answered through other research methods.
Random number generators (RNGs) are widely used in conducting Monte Carlo simulation studies, which are important in the field of statistics for comparing power, mean differences, or distribution shapes between statistical approaches. Statistical results, however, may differ when different random number generators are used. Often older methods have been blindly used with no understanding of their limitations. Many random functions supplied with computers today have been found to be comparatively unsatisfactory. In this study, five multiplicative linear congruential generators (MLCGs) were chosen which are provided in the following statistical packages: RANDU (IBM), RNUN (IMSL), RANUNI (SAS), UNIFORM(SPSS), and RANDOM (BMDP). Using a personal computer (PC), an empirical investigation was performed using five criteria: period length before repeating random numbers, distribution shape, correlation between adjacent numbers, density of distributions and normal approach of random number generator (RNG) in a normal function. All RNG FORTRAN programs were rewritten into Pascal which is more efficient language for the PC. Sets of random numbers were generated using different starting values. A good RNG should have the following properties: a long enough period; a well-structured pattern in distribution; independence between random number sequences; random and uniform distribution; and a good normal approach in the normal distribution. Findings in this study suggested that the above five criteria need to be examined when conducting a simulation study with large enough sample sizes and various starting values because the RNG selected can affect the statistical results. Furthermore, a study for purposes of indicating reproducibility and validity should indicate the source of the RNG, the type of RNG used, evaluation results of the RNG, and any pertinent information related to the computer used in the study. Recommendations for future research are suggested in the area of other RNGs and methods not used in this study, such as additive, combined, …
The purpose of this study was to explore the correlation of stress and job satisfaction among urban special education teachers. A stress inventory, Maslach Burnout Inventory, a job satisfaction questionnaire, Minnesota Job Satisfaction Questionnaire, and a demographic profile were used to survey 292 special needs teachers.
The purpose of this study was to determine whether there were differences in the levels of awareness and perception concerning distance education among the leadership at the seven campuses of the Texas State Technical College (TSTC) System.
This research study was designed to investigate whether authentic assessment in written language is a valid assessment tool for students with and without learning disabilities. Teacher judgements were used to evaluate students' authentic writing assessments gathered from the classroom. Students' report card grades, authentic writing assessments, and two standardized writing assessments, the Test of Written Language- Revised and Written Language Assessment, were correlated to provide evidence of the validity of authentic assessment practices in written language.
Recent research in juvenile justice has focussed on identifying precursors of delinquency, which are referred to as "risk factors." These are biological or psychosocial conditions that increase the probability of an individual developing problem behaviors. Delinquency prevention and intervention programs are adopting a risk-focussed approach which attempts to reduce targeted youth's exposure to risk factors. Limited attention has been paid to investigating whether commonly accepted risk factors are equally relevant across various subtypes of juvenile offenders. Two subgroups of offenders deserving of special attention by virtue of their extremely high prevalence rates in the juvenile justice system are those with emotional/behavioral disorders (EBD) and those with learning disabilities (LD). The purpose of this study was to determine the relevance of specific individually-, family-, and school-based risk factors for delinquency across three specific groups of juvenile offenders: (a) those with EBD, (b) those with LD, and (c) those who did not qualify as disabled under the definition of disability used in the Individuals with Disabilities Education Act (IDEA). Individual risk factors that were measured included aggressive/acting-out behaviors, irresponsible/inattentive behaviors, fearful/anxious behaviors, social withdrawn behaviors, age at first arrest and history of substance use. School-based risk factors examined were students' reading and math scores and attitude towards and involvement in school. Attachment to family, parental discipline style, and level of supervision provided by parents were the family-based risk factors examined. Discriminant analysis procedures indicated that juvenile offenders with EBD, juvenile offenders with LD, and nondisabled offenders differed significantly in their demonstration of aggressive/acting-out behaviors, irresponsible/inattentive behaviors and fearful/anxious behaviors. In contrast, no significant differences were found across family-, and school-based risk factors. This implies that until research demonstrates the existence of unique risk factors or a difference in the magnitude of risk factors experienced by juvenile offenders with EBD and LD, it …
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 purpose of this study was to investigate the effects of self-management strategies as a means of reducing off-task and disruptive behaviors of elementary school children identified as emotionally disturbed or behavior disordered (E/BD). This study provided a practical approach for classroom teachers to implement self-management strategies in classes that include children identified as having E/BD. Five elementary school children who were formally evaluated and enrolled in a special education classroom for students with E/BD were selected to participate in the study. The study also examined the effects of the self-management procedures when targeted behaviors were monitored by peers. Four resource students from the regular education class served as peer monitors. An ABAB reversal design was used to assess the effectiveness of the self-management strategy in the special education classroom. A behavior rating scale was used at the beginning of the study to develop a baseline of student behavior and during the final phase of the intervention to measure progress. The data indicated that the self-management strategies decreased the levels off-task and disruptive behaviors for all participating students. The findings of this study substantiates previous research that suggests self-management techniques help student to manage their own behaviors.
The purpose of this study was to determine whether training had an impact on the information technology attitudes of university faculty. The study was twofold. First, it sought to determine whether training changed attitudes toward information technology among faculty at a small, liberal arts university. Secondly, a group of faculty at a similar university was used to compare the differences in attitudes toward information technology among faculty who had received training and those who had not. The research population consisted of 218 faculty from these two universities. The literature review focused on obstacles to information technology use by faculty, instruments currently available for measuring faculty attitude, methods used in training faculty to use information technology, and integration of information technology by faculty.
The study examined the effects of a study skills training intervention course on U.S. Air Force Aeromedical Apprentices with five main purposes. The first was to examine the relationship between study skills training and the number of times students required academic interventions outside of normal class time. The second purpose was to examine the relationship between study skills training and end of course averages. The third was to determine the relationship between study skills training and the amount of additional instruction, measured in time, students required. The fourth purpose examined the relationship between study skills training and graduation rates. The final purpose was to recommend areas for further research.
With the growing use of teams in organizations and schools there is a need to better understand the individual differences of employees that might potentially increase performance and improve attitudes. The purpose of this study was to assess the impact of locus of control, which was the individual difference of interest in this study, and incentives on team performance and job satisfaction.
The purpose of this study was to delineate the differences between the types of behavioral management techniques used by teachers of students with emotional/behavioral disorders.
Proponents of special education early childhood interventions programs have promoted the assumptions that these programs: (a) will have a positive effect on the long-term outcomes of preschool children with disabilities; (b) will result in some children no longer requiring special education services throughout their elementary school years; and (c) will facilitate the need for fewer services for those students who do remain in special education programs throughout their education. The purpose of this follow-up study is to identify and describe the placement decisions and the changes of exceptionality classification for children identified as special education early childhood students over the course of six follow-up years. This study (a) identifies 108 children from rural and urban school settings who were enrolled in Early Childhood Special Education (ECSE) programs in 1990-91, (b) documents their categorical label and educational placement six years later, and (c) then determines the differences in the number of hours rural and urban students receive special education and/or related services in 1996-97.
Differential item functioning (DIF) detection rates were examined for the logistic regression and analysis of variance (ANOVA) DIF detection methods. The methods were applied to simulated data sets of varying test length (20, 40, and 60 items) and sample size (200, 400, and 600 examinees) for both equal and unequal underlying ability between groups as well as for both fixed and varying item discrimination parameters. Each test contained 5% uniform DIF items, 5% non-uniform DIF items, and 5% combination DIF (simultaneous uniform and non-uniform DIF) items. The factors were completely crossed, and each experiment was replicated 100 times. For both methods and all DIF types, a test length of 20 was sufficient for satisfactory DIF detection. The detection rate increased significantly with sample size for each method. With the ANOVA DIF method and uniform DIF, there was a difference in detection rates between discrimination parameter types, which favored varying discrimination and decreased with increased sample size. The detection rate of non-uniform DIF using the ANOVA DIF method was higher with fixed discrimination parameters than with varying discrimination parameters when relative underlying ability was unequal. In the combination DIF case, there was a three-way interaction among the experimental factors discrimination type, relative ability, and sample size for both detection methods. The error rate for the ANOVA DIF detection method decreased as test length increased and increased as sample size increased. For both methods, the error rate was slightly higher with varying discrimination parameters than with fixed. For logistic regression, the error rate increased with sample size when relative underlying ability was unequal between groups. The logistic regression method detected uniform and non-uniform DIF at a higher rate than the ANOVA DIF method. Because the type of DIF present in real data is rarely known, the logistic regression method is recommended for …
This study identified the attitudes of paraeducators toward students with disabilities and the implications for staff development. The purpose of this study was to survey attitudes of paraeducators toward students with disabilities. The attitude and demographic information obtained through the survey were analyzed for its implications for staff development with paraeducators.
This study had a two-fold purpose. The first purpose was to compare the rankings of a set of knowledge/skills statements as reported by teachers of students with emotional behavioral disorders and teachers in juvenile correctional special education settings. A survey instrument designed to measure the importance, proficiency, and frequency of use of clusters of knowledge/skills statements was administered to 123 teachers in juvenile correctional special education settings in state institutions. Mann Whitney U analyses were calculated to compare the mean rankings of the two groups of teachers. The findings indicated that teachers in juvenile correctional special education settings and teachers of students with emotional and behavioral disorders were very similar as to which knowledge/skills clusters were important to their job performance, which clusters they were most proficient at using, and which clusters they utilized most frequently. The second purpose was to compare the teachers in juvenile correctional special education settings and to determine whether their mean rankings of the knowledge/skills clusters varied when analyzed by differing categories of age, type of certification held, years of teaching experience, and level of the teachers' education. Analysis of variance revealed no significant difference in the mean rankings in any of the comparison groups. Therefore teacher age, level of education, type of certification held, or years of teaching experience yielded no significant differences on the mean rankings of the knowledge/skills clusters.
This study examined the effects of test anxiety reduction strategies on U.S. Air Force allied health care students and had a fourfold purpose. The first was to estimate the extent of student test anxiety in allied health care students. The second was to determine the predictors of student test anxiety. The third was to determine if the Student Learning Center provides an effective method of reducing test anxiety in the subjects. The final purpose was to recommend areas for future research.
Research has reported that a predictive link exists between socio-economic risk factors and high school dropouts, including teen-aged parents. Educators have little control over socio-economic risk factors. However, school records and classroom performance data can point to in-school risk factors. The purpose of this study was to help all students by using the in-school data to pinpoint the indicators that predict potential student achievement difficulties in specific areas of curricula. This study was an anteriospective longitudinal study of the 1995 graduating class of a suburban school district composed of approximately 920 seniors. The sample consisted of 344 graduates, 114 dropouts, and 42 teenaged parents. Backward stepwise logistic regression analysis was the statistical method used for model building. An analysis was done by gender at the 2nd, 4th, 6th, and 8th grades from the permanent records of sample students. The study found that significant predictors exist at each grade level and are different for each group, grade level, and gender with some predictors in common: language arts and attendance. The most consistent male dropout predictors were found to be absenteeism, grades in language arts, spelling, and achievement test scores in language arts. The most consistent female dropout predictors were found to be absenteeism, elementary retention, course failures, and achievement test scores in language arts. Achievement test scores in language arts were found to be the most important in-school predictors for teen-aged parents. The predictors for teenaged parents followed the same pattern as female dropouts and graduates until the 8th grade where achievement test scores in vocabulary, math, and total battery became important predictors. Teen-aged parents were found to be a sub-population of dropouts or graduates. Teen-aged parents dropped out or graduated from school based on the early predictors of dropouts or graduates, not based on parenting or single status.
In the present study, parameter estimates, standard errors and chi-square statistics were compared using normal and elliptical estimation methods given three research conditions: population data contamination (10%, 20%, and 30%), sample size (100, 400, and 1000), and kurtosis (kappa =1,10, 20).
Discrete-time survival analysis as an educational research technique has focused on analysing and interpretating parameter estimates. The purpose of this study was to examine the effects of certain data characteristics on the hazard estimates and goodness of fit statistics. Fifty-four simulated data sets were crossed with four conditions in a 2 (time period) by 3 (distribution of Y = 1) by 3 (distribution of Y = 0) by 3 (sample size) design.
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.
This study assessed the predictive validity of four independent factors (Rotter Locus of Control Scale, Safety Locus of Control, Organizational Attribution Style Questionnaire, and Rosenburg Self-Esteem Scale) in the establishment of a measure of safety consciousness in predicting on-the-job injuries and the filing of workers' compensation claims. A 125-item questionnaire was designed and administered to assess participants' disposition on each of the four psychological dimensions, demographic data and on-the-job injury information.
This study researched effect of selected demographic variables on the self-perceived competencies of career counselors at secondary and post secondary institutions in Texas. Demographic variables were years of service, educational level, type of institution, age of counselor, size of institution, and percentage of vocational enrollment. One hundred career counselors, fifty secondary and fifty post secondary career counselors were mailed copies of the Professional Needs Assessment and a Demographic questionnaire.
The purpose of this study was to focus on the Omnibus Budget Reconciliation Act of 1987 and the amendments of 1989 and 1990. Nursing assistants were placed in cluster groups of 300-hours, 120-hours, and 0-hours. Each subject's job performance of nursing care was observed using the Francis's Task Performance Rating Scale. The purpose of the analysis was to determine (1) if there was a significant difference in job performance of patient care between program completers and the challengers, (2) if there was a significant difference in the job performance of patient care between 300-hour and 120-hour, and (3) if there was a significant difference between the content required in OBRA mandated nursing assistant programs and actual job performance skills needed in patient care. It was determined that program completers' job performance of patient care was significantly different from the challengers.
Researchers who make predictions from educational data are interested in choosing the best regression model possible. Many criteria have been devised for choosing a full or restricted model, and also for selecting the best subset from an all-possible-subsets regression. The relative practical usefulness of three of the criteria used in selecting a regression model was compared in this study: (a) Mallows' C_p, (b) Amemiya's prediction criterion, and (c) Hagerty and Srinivasan's method involving predictive power. Target correlation matrices with 10,000 cases were simulated so that the matrices had varying degrees of effect sizes. The amount of power for each matrix was calculated after one or two predictors was dropped from the full regression model, for sample sizes ranging from n = 25 to n = 150. Also, the null case, when one predictor was uncorrelated with the other predictors, was considered. In addition, comparisons for regression models selected using C_p and prediction criterion were performed using data from the National Educational Longitudinal Study of 1988.
The purpose of this study was to determine reliability estimates of authentic assessment for fourth-grade narrative and descriptive writing samples for students with and without learning disabilities. Three types of reliability estimates were established: (a) inter-rater, (b) score stability, and (c) alternate-form. The research design involved 40 teachers, trained in holistic scoring by Education Service Centers 10 and 11 in Dallas and Fort Worth, Texas, who scored 16 writing samples. Approximately 2 weeks later the teachers rescored 8 of the same writing samples. In addition to scoring the writing samples, the teachers also completed a demographic questionnaire. The writing samples, which consisted of eight narrative and eight descriptive writings, were selected based upon teachers' holistic scores and scores from 1993 writing sample of the Texas Assessment of Academic Skills. Based upon these scores, two narrative and descriptive writings of above-average, average, and below-average writings were selected. In addition, two narrative and descriptive writing samples of students with learning disabilities in written language were selected.
