- The Developmental Characteristics of Young Children Prenatally Substance-exposed
- The purpose of this study was to explore the developmental characteristics of young children (ages 11-60 months) with prenatal substance-exposure. A developmental rating scale, the Developmental Checklist (DC) of the Developmental Observation Checklists (DOCs) was utilized. The DC measures the domains of language, motor, social/behavioral, and cognition, as well as overall developmental status.
- A Comparison of Traditional Norming and Rasch Quick Norming Methods
- The simplicity and ease of use of the Rasch procedure is a decided advantage. The test user needs only two numbers: the frequency of persons who answered each item correctly and the Rasch-calibrated item difficulty, usually a part of an existing item bank. Norms can be computed quickly for any specific group of interest. In addition, once the selected items from the calibrated bank are normed, any test, built from the item bank, is automatically norm-referenced. Thus, it was concluded that the Rasch quick norm procedure is a meaningful alternative to traditional classical true score norming for test users who desire normative data.
- Preservice Teacher Attitudes towards Nonvocal Individuals using High Technology Augmentative Communication Devices versus Low Technology Communication Boards
- The attitudes of preservice teachers towards individuals who are nonvocal and using either a high technology augmentative communication (HAC) device or a low technology communication board were investigated. A rating scale was devised, consisting of three sub-scales. The three sub-scales measured preservice teachers' estimates of intelligence, academic potential, and social acceptance in the regular education setting. Reliability and validity were established through a pilot study. Preservice teachers viewed videotapes of children using either high technology or low technology augmentative communication devices and subsequently completed the rating scale based on the videotapes. Results indicated that preservice teachers perceived the same child as having greater academic and social acceptance potential when using high technology augmentative communication.
- The Effects of Supplemental Performance and On-Task Contingencies on the Acquisition of Math Skills for Elementary School Students with Behavioral Disorders, Students with Attention Deficit Disorders, and Students without Disabilities
- The purpose of this study was to investigate the effects of supplemental on-task and performance contingencies on the acquisition of math skills for elementary school children identified as seriously emotionally disturbed/behaviorally disordered, attention deficit disordered, and students without disabilities. Three experimental conditions were utilized, involving teacher-directed instruction with (a) no contingencies, (b) contingencies for academic performance, and (c) contingencies for academic performance and on-task behavior. The study was designed to measure the effects of these contingency conditions on the number of math problems solved accurately by the study's participants.
- Outliers and Regression Models
- The mitigation of outliers serves to increase the strength of a relationship between variables. This study defined outliers in three different ways and used five regression procedures to describe the effects of outliers on 50 data sets. This study also examined the relationship among the shape of the distribution, skewness, and outliers.
- An Examination of Regular Education Elementary Teachers' Attitudes Toward Students with Emotional/Behavioral Disorders
- This study examined the attitudes of regular education teachers at the elementary school level, toward mainstreaming students with emotional/behavioral disorders (E/BD) and identified variables which were correlated with those attitudes.
- Using an Eigenvalue Distribution to Compare Covariance Structure Matrices
- The problem of this study was to seek a goodness-of-fit index to compare covariance structure matrices based on the distribution of the mean of the logarithms of the eigenvalues.
- Analysis of Critical Skills Used By Educators of Students With Autism
- A review of the literature indicated that critical skills needed by educators of students with autism had not been sufficiently identified. Research efforts using survey instruments appeared to offer a method for gathering data in order to develop and analyze a comprehensive list of critical skills for educators of students with autism. A survey instrument was developed in bifurcate format that required respondents to rate 118 skill items according to Importance and Proficiency. Two Likert-type scales were provided to enable respondents to record their perceptions of Importance and Proficiency. The instrument was mailed to a nationwide stratified sample of educators of students with autism. A total of 90 surveys were mailed with 52 (57%) returned. Four hypotheses and two research questions were developed. Data were analyzed using MANOVA to test for significant differences among the four geographic regions of the United States and within ten skill areas. The findings did not support the hypotheses; therefore, all hypotheses were rejected. In further analysis utilizing the ANOVA and Chi-Square procedures, significant differences among some regions and within some of the skill areas were found. The findings suggest that educators from the four regions tended to differ in regard to Importance and Proficiency for certain skill items. Findings led to recommendations being given relevant to future research on critical skills needed for teachers in the field of autism.
- Influence of Item Response Theory and Type of Judge on a Standard Set Using the Iterative Angoff Standard Setting Method
- The purpose of this investigation was to determine the influence of item response theory and different types of judges on a standard. The iterative Angoff standard setting method was employed by all judges to determine a cut-off score for a public school district-wide criterion-reformed test. The analysis of variance of the effect of judge type and standard setting method on the central tendency of the standard revealed the existence of an ordinal interaction between judge type and method. Without any knowledge of p-values, one judge group set an unrealistic standard. A significant disordinal interaction was found concerning the effect of judge type and standard setting method on the variance of the standard. A positive covariance was detected between judges' minimum pass level estimates and empirical item information. With both p-values and b-values, judge groups had mean minimum pass levels that were positively correlated (ranging from .77 to .86), regardless of the type of information given to the judges. No differences in correlations were detected between different judge types or different methods. The generalizability coefficients and phi indices for 12 judges included in any method or judge type were acceptable (ranging from .77 to .99). The generalizability coefficient and phi index for all 24 judges were quite high (.99 and .96, respectively).
