在高三物理复习课中,试题讲评是课堂的重要组成部分。为提升学生的解题能力,减轻学生的学习负担,提高复习的效率,在讲评时对学生错误率高的问题可进行适当的变式处理,即通过恰当地变更问题探究角度、情境或模型,精心设计相关问题,使学生领悟解决相关问题的方法,从而达到“跳出题海”“减负增效”的美好目的。 In the third year physics review class, the test comment is an important part of the class. In order to enhance the ability of students to solve problems, reduce the students’ study burden and improve the efficiency of reviewing, we can appropriately deal with the problem of high error rate of students when commenting, that is, by properly changing the angle, situation or model of question probing, Meticulous design of related issues, so that students understand the methods of solving problems, so as to achieve the beautiful purpose of “jumping out of the question sea ” “reduce the negative effect”.
