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…

A review of four areas in which the computer has influenced the theory and practice of achievement testing: a) test scoring and item analysis, b) item sampling, c) item generation, and d) the sequencing of items resulting in various types of adaptive testing. Also, reference is made to the impact of computer assisted achievement testing upon the…

A replicable process for improving instruction through the consistent use of student data collected before, during, and after instruction is proposed. A rational analysis of different types of error rates (theoretical, base, posttest, instructional) and discrimination indices (base, posttest) leads to a set of rules for identifying test items and…

The author analyzes properties of mutual information between dichotomous concepts and test items. The properties generalize some common intuitions about item comparison, and provide principled foundations for designing item-selection heuristics for student assessment in computer-assisted educational systems. The proposed item-selection strategies…
