多肢選択テストの部分的知識による得点増加を評価するための数学モデル

Abstract

To assess the contribution of the partial knowledge of examinees to the scores of multiple-choice tests, we have proposed two mathematical models, the Binary-model and the Terminal model. These models both were based on the probability with which an examinee recognizes a choice correctly, and on the arrangement of choices. As an application of these models, the distributions of scores were given for the one-best-response type and the two-responses type of questions of the national board examinations for the medical and dental practices. The distributions of scores by these two models were compared.
