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…

This study elaborates the "what works?" question by exploring the effects of variability in program implementation quality on achievement. Particularly, the effects on achievement of computerized assessment of reading were investigated, analyzing data on 51,000 students in Grades 1-12 who read over 3 million books. When minimum implementation…

Item analysis procedures appropriate for domain-referenced classroom testing are described. A conceptual framework within which item statistics can be considered and promising statistics in light of this framework are presented. The sampling fluctuations of the more promising item statistics for sample sizes comparable to the typical classroom…

The purpose of this paper is to describe some of the current changes in test development that are taking place because of the availability and capabilities of computers, especially microcomputers. Item banking and test assembly are discussed, and a comprehensive testing system is described. (BW)

In connection with the development of item pools for the Navy's experimental Computerized Adaptive Testing (CAT) system, items in five different content areas (General Science, Paragraph Composition, Word Knowledge, Math Knowledge, and Arithmetic Reasoning) have been calibrated using item response theory (IRT) methodology. Operational Armed…

In every instance in the process of constructing and using a test, the microcomputer can aid the classroom teacher. However, the teacher will not apply the microcomputer to classroom testing without added training both in classroom testing and in using the microcomputer. (BW)

CSAR (Characteristic Storage And Retrieval) is the name of an interactive item bank system for the storage, retrieval, manipulation, and summarization of information about multiple choice test items. The purpose of the system is to facilitate the test construction process. The system has two main components: one or more item banks and an…

The author argues that scoring, reporting, and deriving final grades can be considerably assisted by using a computer. He also contends that the savings in time and the computer database formed will allow instructors to determine test quality and reflect on the quality of instruction. (BW)

The purpose of this paper is to present two new alternative methods to the current goodness of fit methodology. With the increase use of computerized adaptive test (CAT), the ability to determine the accuracy of calibrated item parameter estimates is paramount. The first method applies a normalizing transformation to the logistic residuals to make…

This research program was designed to investigate the applications of item response theory and computerized adaptive testing to the unique problems of the measurement of ability and the measurement of achievement. The research utilized a combination of monte carlo simulation studies and live-testing studies. The research approach for adaptive…

Student achievement test scores were compared and equated, using three different testing methods: paper-administered, computer-administered, and computerized adaptive testing. The tests were developed from third and sixth grade mathematics item banks of the California Assessment Program. The paper and the computer-administered tests were identical…

The feasibility of creating an item bank from a teacher-made test was examined in two comparable sections of a graduate-level introductory measurement course. The 67-item midterm examination contained multiple-choice and master matching items, which required higher level cognitive processes such as application and analysis. The feasibility of…

Before an item bank is constructed, several curriculum and testing considerations should be addressed. Such issues include the number of students enrolled in the selected subject area; number of desired objectives and items per objective; method of storing the items; and how and when to train how many teachers in item writing. The following steps…

This report contains the Proceedings of the 1982 Item Response Theory and Computerized Adaptive Testing Conference. The papers and their discussions are organized into eight sessions: (1) "Developments in Latent Trait Theory," with papers by Fumiko Samejima and Michael V. Levine; (2) "Parameter Estimation," with papers by…
