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 … more

Preservice Teacher Attitudes towards Nonvocal Individuals using High Technology Augmentative Communication Devices versus Low Technology Communication Boards

Description: 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 t… more

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 academ… more

Outliers and Regression Models

Description: 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.

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… more

Influence of Item Response Theory and Type of Judge on a Standard Set Using the Iterative Angoff Standard Setting Method

Description: 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. With… more
