錯乱肢の種類が語彙テストにおける消去法ストラテジーの使用に及ぼす影響

The aim of this study was to explore whether the use of elimination strategies differed with the change of distractors in multiple-choice vocabulary tests in sentential context. The distractors were classified into two frequency levels and into three different types, and the participants thought aloud while answering the test. Participants' elimination strategies were coded into four types, and the results showed that frequency of elimination uses did not differ with any change of distractors. In other words, the uses of elimination strategies were constant across any types of items this study adopted. However, there was a critical difference between types of elimination (i.e., informed elimination and random elimination) regarding their roles on the test performance. When participants adopted random elimination, the results of the test were totally different from the overall test performance, but this was not the case in terms of informed elimination. The findings implied that random elimination has a strong influence on the construct of tests; hence, it is necessary to create tests that reduce the use of random elimination as far as possible.
