A Comparison of Traditional Norming and Rasch Quick Norming Methods

Description: 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.

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

Description: 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.

The Developmental Characteristics of Young Children Prenatally Substance-exposed

Description: 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.

Analysis of Critical Skills Used By Educators of Students With Autism

Description: 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.
