Graduate medical students often get less opportunity for clarifying their doubts and to reinforce their concepts after lecture classes. The Medical Council of India (MCI) encourages group discussions among students. We evaluated the effect of identifying mistakes in a given set of wrong statements and their correction by a small group discussion by graduate medical students as a revision exercise.
At the end of a module, a pre-test consisting of multiple-choice questions (MCQs) was conducted. Later, a set of incorrect statements related to the topic was given to the students and they were asked to identify the mistakes and correct them in a small group discussion. The effects on low, medium and high achievers were evaluated by a post-test and delayed post-tests with the same set of MCQs.
The mean post-test marks were significantly higher among all the three groups compared to the pre-test marks. The gain from the small group discussion was equal among low, medium and high achievers. The gain from the exercise was retained among low, medium and high achievers after 15 days.
Identification of mistakes in statements and their correction by a small group discussion is an effective, but unconventional revision exercise in biochemistry.
医学研究生在课程讲授之后，往往很少有机会澄清疑问并强化概念。印度医学委员会（MCI）鼓励学生进行小组讨论。我们评估了医学研究生通过小组讨论来识别给定错误陈述中的错误并加以纠正这一复习练习的效果。
在一个模块结束时，进行了一次包含多项选择题（MCQ）的预测试。之后，向学生提供一组与该主题相关的错误陈述，要求他们在小组讨论中识别错误并进行纠正。通过使用同一组MCQ进行后测和延迟后测，评估对低、中、高成绩者的影响。
与预测试成绩相比，所有三组的后测平均成绩均显著更高。低、中、高成绩者从小组讨论中获得的收益相同。15天后，低、中、高成绩者都保留了此次练习的收获。
通过小组讨论识别陈述中的错误并加以纠正，是生物化学中一种有效但非传统的复习练习。
