In selected-response assessments such as attitude surveys with Likert-type rating scales, examinees often select from rating scale categories to reflect their locations on a construct. Researchers have observed that some examinees exhibit "response styles," which are systematic patterns of responses in which examinees are more likely to…

This article aims to provide a theoretical framework for computerized adaptive tests (CAT) and item response theory models for polytomous items. Besides that, it aims to introduce the simulation and live CAT software to the related researchers. Computerized adaptive test algorithm, assumptions of item response theory models, nominal response…

This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

In circumstances where judges are required to make ratings of performance, it is usually required to have two or more raters who are trained to agree on independent ratings of the same performance. It is suggested that such a requirement may produce the paradox of attenuation associated with item analysis, in which too high a correlation between…

This report describes the procedures used to construct and validate the Standardized Test of Computer Literacy (STCL), a criterion-referenced instrument designed to assess students' computer literacy. Following a statement of the study problem and purpose, a description of the study methodology outlines the use of a 12-step model for development…

Purposes of this study were: (1) to examine patterns of implementation of an innovative educational program with a built-in staff development component over a period of three years; (2) to compare patterns of implementation of the Adaptive Learning Environments Model's (ALEM) three types of teaching skills, including generic, adaptive, and program…
