背景资料：纯文本多项选择题（MCQ）通常不足以评估解剖学和组织学知识，并可能鼓励学生记忆抽象的教科书知识。另一种方法是在北美和英国解剖学中众所周知的“观察者”或“标记测试”。然而，这种评估的心理测量学特性仅在一项研究中报告了使用简短回答问题的格式。目的：描述使用解剖标本、组织学切片、模型和X光片的多项选择“标签测试”（3D-MC）的实施和可行性;报告3D-MC的心理测量学特性和学生对3D-MC的接受程度;将其与传统的多项选择格式进行比较。结果：3D-MC的管理没有造成任何重大问题。3D-MC明显比传统MCQ更容易（平均得分75% vs. 64%）。两种MCQ格式之间的估计相关性（校正衰减）为r = 0.814。3D-MC的可靠性为。30件商品665美元。学生接受度非常高。结论：3D-MC是一种可行的、可靠的、被广泛接受的解剖知识测试。进一步的研究应调查，与使用照片的多学科技能问卷相比，对不同知识和能力的评估是否证明了与使用照片的多学科技能问卷相比更高的成本是合理的。
Background: Text only multiple choice questions (MCQs) are often inadequate to assess anatomical and histological knowledge and may encourage students to memorize abstract textbook knowledge. An alternative are the “spotters” or “tag tests” well-known in North American and British anatomy. However, the psychometric properties of this assessment have only been reported in one study for a format using short answer questions. Aims: To describe the implementation and feasibility of a multiple choice “tag test” (3D-MC) using prosected specimens, histological slides, models and radiographs; to report the psychometric properties and students' acceptance of the 3D-MC; to compare it with a traditional multiple choice format. Results: The administration of the 3D-MC did not pose any major problems. The 3D-MC was significantly easier (mean scores 75% vs. 64%) than traditional MCQs. The estimated correlation (corrected for attenuation) between the two MCQ formats was r = 0.814. Reliability for the 3D-MC was. 665 for 30 items. Student acceptance was very high. Conclusions: The 3D-MC is a feasible, reliable and well-accepted test of anatomical knowledge. Further research should investigate if the higher cost as compared to MCQs using photographs is justified by the assessment of different knowledge and abilities as compared to MCQs using photographs.
