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…

Although the development of process skills has been accepted as being an important part of elementary school curricula in science and in other subjects, few valid and reliable tests exist for their assessment. Therefore, a test is currently being developed to assess these skills. It is designed to meet seven criteria (such as testing process…

This paper points out that there are certain generalizations about directions for guessing and methods of scoring that require that data be derived from random groups design. It supports the viewpoint that it is neither sufficient nor appropriate to make such generalizations on the basis of an analysis of scores obtained from the answer sheets of…

Two matched forms of a 50 item grammar test were developed. Twenty items designed to be humorous were included in one form. Inclusion of humorous items did not affect grammar scores on matched humorous/nonhumorous items, nor on commmon post-treatment items. Inclusion did not affect results of anxiety measures.

Presents a validation procedure for the Computer Literacy Examination: Cognitive Aspect, a test assessing high school students' computer literacy levels. Steps in the test's construction process are explained, data collected during its validation phase are analyzed, and conclusions on its validity and reliability are discussed. The final test…

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…

Specific questions addressed in this study include how time limits affect a test's construct and predictive validities, how time limits affect an examinee's time allocation and test performance, and whether the assumption about how examinees answer items is valid. Interactions involving an examinee's sex and age are studied. Two parallel forms of…
