Timed Testing: An Approach Using Item Response Theory

Publisher Summary This chapter describes the use of an item response model for item analysis and test scoring in the context of timed testing. The chapter describes a model that is a revision of a model proposed by Furneaux. Furneaux described the outline of the model and provided some illustration of the performance of parts of the system with a small set of test data, using parameters estimated by various heuristic procedures. The chapter describes the outcome of timed testing with several different kinds of test items by using a slightly different model and an integrated parameter estimation scheme . A complete system for scoring timed tests requires an item response model for the data of timed testing: the responses and the associated latencies.
