词缀知识对词汇知识的发展和词汇习得起着至关重要的作用。词缀知识水平的诊断信息测试将是有用的，以告知测试用户的学习者已经获得或缺乏在这个组成部分的词汇知识。本文报告了Sasao和Webb（2017）创建的Word Part Levels Test（WPLT）的计算机化自适应测试（CAT）版本的开发和评估。开发CAT-WPLT是为了进一步最大化WPLT作为诊断测试的有效性。它被管理到760名日本大学EFL（英语作为外语）学习者。该评估是基于与固定项目版本的WPLT的测量准确度的比较。结果表明，CAT-WPLT能以较少的项目数和相同或更高的准确度为测试者提供关于受试者词缀知识优势和劣势的诊断信息。沿着利用计算机自适应的问题，使用CAT-WPLT的教学意义进行了讨论。
The knowledge about affix plays a vital role in the development of word knowledge and vocabulary acquisition. A test for diagnostic information on the level of affix knowledge would be useful in order to inform the test users of what learners have gained or lacked in this integral component of vocabulary knowledge. This paper reports the development and evaluation of a computerized adaptive testing (CAT) version of the Word Part Levels Test (WPLT), created by Sasao and Webb (2017). The CAT-WPLT was developed to maximize further the effectiveness of the WPLT as a diagnostic test. It was administered to 760 Japanese university EFL (English as a foreign language) learners. The evaluation was based on the comparison of measurement accuracy with the fixed-item version of the WPLT. The results show that the CAT-WPLT can provide test users with diagnostic information on test-taker's strengths and weaknesses in affix knowledge with smaller number of items and with the same or greater precision than the previous versions of the WPLT. Pedagogical implications for using the CAT-WPLT are discussed along with issues in utilizing computer adaptivity.
