A written examination based on material covered in the first year of medical school (anatomy, physiology, biochemistry, and neuroscience) was administered to medical students immediately before they began the pathology course to assess their knowledge of the basic science content that is important for the study of pathology. In alternate years the questions were presented in the standard multiple choice question (MCQ) format or in an open-ended, uncued question (Un-Q) format. The students' mean scores obtained by these two testing methods were comparable. The discrimination indices, which measure the ability of the test questions to distinguish between students of varying ability, were comparable. The Kuder-Richardson Formula 20 (KR-20), an estimate of the precision of the test given, was 0.53 for MCQ and 0.63 for Un-Q. We conclude that the Un-Q format is an acceptable alternative to the MCQ format and it has several advantages over MCQ. Because the answer sheets for Un-Q tests can be scanned optically and graded by computers, we recommend them as an alternative to MCQ tests.
在医学生开始病理学课程之前，对他们进行了一次基于医学院校一年级所学内容（解剖学、生理学、生物化学和神经科学）的书面考试，以评估他们对病理学学习至关重要的基础科学知识的掌握情况。每隔一年，问题以标准的多项选择题（MCQ）形式或开放式、无提示问题（Un-Q）形式呈现。通过这两种测试方法获得的学生平均成绩相当。衡量试题区分不同能力学生能力的区分指数相当。库德-理查森公式20（KR-20）对给定测试精度的估计，MCQ为0.53，Un-Q为0.63。我们得出结论，Un-Q形式是MCQ形式的一种可接受替代方案，并且它比MCQ有几个优点。由于Un-Q测试的答卷可以进行光学扫描并由计算机评分，我们建议将其作为MCQ测试的替代方案。
