Assessment of the Perceived Competencies Possessed by Women Administrators in Vocational Education at Community Colleges in Texas

Assessment of the Perceived Competencies Possessed by Women Administrators in Vocational Education at Community Colleges in Texas

Date: May 1997
Creator: Chiawa, Chioma B. (Chioma Bernadette)
Description: 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 ...

A Comparison of a Computer-Administered Test and a Paper and Pencil Test Using Normally Achieving and Mathematically Disabled Young Children

Date: May 1997
Creator: Swain, Colleen R. (Colleen Ruth)
Description: 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.

A Comparison of Knowledge/Skills Statements Needed by Teachers of Students with Emotional and Behavioral Disorders and Teachers in Juvenile Correctional Special Education Settings

A Comparison of Knowledge/Skills Statements Needed by Teachers of Students with Emotional and Behavioral Disorders and Teachers in Juvenile Correctional Special Education Settings

Date: December 1994
Creator: McArthur, Patrick L. (Patrick Lee)
Description: 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. ...

A Comparison of Three Criteria Employed in the Selection of Regression Models Using Simulated and Real Data

A Comparison of Three Criteria Employed in the Selection of Regression Models Using Simulated and Real Data

Date: December 1994
Creator: Graham, D. Scott
Description: 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.

A Comparison of Two Differential Item Functioning Detection Methods: Logistic Regression and an Analysis of Variance Approach Using Rasch Estimation

A Comparison of Two Differential Item Functioning Detection Methods: Logistic Regression and an Analysis of Variance Approach Using Rasch Estimation

Date: August 1995
Creator: Whitmore, Marjorie Lee Threet
Description: 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, ...

The Effect of Psychometric Parallelism among Predictors on the Efficiency of Equal Weights and Least Squares Weights in Multiple Regression

The Effect of Psychometric Parallelism among Predictors on the Efficiency of Equal Weights and Least Squares Weights in Multiple Regression

Date: May 1996
Creator: Zhang, Desheng
Description: 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 ...

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.

The Effectiveness of Speech Recognition as a User Interface for Computer-Based Training

The Effectiveness of Speech Recognition as a User Interface for Computer-Based Training

Date: August 1995
Creator: Creech, Wayne E. (Wayne Everette)
Description: 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 ...

Date: August 1995
Creator: Szydlik, Linda (Linda L.)
Description: 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 ...

An Empirical Comparison of Random Number Generators: Period, Structure, Correlation, Density, and Efficiency

An Empirical Comparison of Random Number Generators: Period, Structure, Correlation, Density, and Efficiency

Date: August 1995
Creator: Bang, Jung Woong
Description: 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 ...

A Follow-Up Study of the Subsequent Educational Placement and Categorical Classification of Preschool Early Childhood Special Education Students in Selected Rural and Urban Settings

A Follow-Up Study of the Subsequent Educational Placement and Categorical Classification of Preschool Early Childhood Special Education Students in Selected Rural and Urban Settings

Date: December 1996
Creator: Lechtenberger, DeAnn
Description: 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.
