The process of developing a rubric to assess the cognitive complexity of student-generated multiple choice questions in medical education

摘要

Cognitively complex assessments encourage students to prepare using deep learning strategies rather than surface learning, recall-based ones. In order to prepare such assessment tasks, it is necessary to have some way of measuring cognitive complexity. In the context of a student-generated MCQ writing task, we developed a rubric for assessing the cognitive complexity of MCQs based on Bloom’s taxonomy. We simplified the six-level taxonomy into a three-level rubric. Three rounds of moderation and rubric development were conducted, in which 10, 15 and 100 randomly selected student-generated MCQs were independentlyrated by three academic staff. After each round of marking, inter-rater reliability was calculated, qualitative analysis of areas ofagreement and disagreement was conducted, and the markers discussed the cognitive processes required to answer the MCQs.Inter-rater reliability, defined by the intra-class correlation coefficient, increased from 0.63 to 0.94, indicating the markers rated the MCQs consistently. The three-level rubric was found to be effective for evaluating the cognitive complexity of MCQsgenerated by medical students.
