The research on score comparability across computerized devices is no exception. CCSSO [Council of Chief State School Officers] and the Center for Assessment have published…

When power tests include a time limit, it is important to assess the possibility of speededness for examinees. Past research on differential speededness has examined gender and ethnic subgroups in the United States on paper and pencil tests. When considering the needs of a global audience, research regarding different native language speakers is…

This article explores the effect on assessment of "translating" paper and pencil test items into their computer equivalents. Computer versions of a set of mathematics questions derived from the paper-based end of key stage 2 and 3 assessments in England were administered to age appropriate pupil samples, and the outcomes compared.…

The IRT (Item Response Theory) has been studied and applied in computer-based test for decades. However, almost of all these existing studies evaluated focus merely on test questions with text-based (or static text/graphic) type of presentation form illustrated exclusively. In this paper, we present our study on test questions using both…

Reviews study conducted to compare levels of achievement on final exams for college students responding to combinations of test-item feedback methods and modes of test-item presentation. The PHOENIX computer system used in the comparison is described, and the use of ACT (American College Testing Program) scores for ability comparison is discussed.…
