本研究旨在开发两种等价的语境猜测测验（GCT），并提供其初步的效度证据。GCT是对猜测技能的诊断性测试，测量猜测中的以下三个重要步骤：识别未知词的词性，找到其话语线索，推导其含义。该测试对428名日本英语学习者进行了测试。结果表明，这两种形式各有20个问题集，在项目难度分布和被测结构的代表性方面是等效的。使用Messick的验证框架，Rasch模型，对实际猜测的关系进行定性调查，并提出分数解释的建议，提供了广泛的有效性证据。
This study aims to develop two equivalent forms of the Guessing from Context Test (GCT) and provide its preliminary validity evidence. The GCT is a diagnostic test of the guessing skill and measures the following three important steps in guessing: identifying the part of speech of an unknown word, finding its discourse clue, and deriving its meaning. The test was administered to 428 Japanese learners of English. The results indicate that the two forms each with 20 question sets are equivalent in terms of item difficulty distribution and representativeness of the construct being measured. A wide range of validity evidence was provided using Messick’s validation framework, the Rasch model, qualitative investigations into the relationships to actual guessing, and proposals for score interpretation.
