题海战术经常让习题教学躺枪,但是毋庸讳言,习题依然是当下学生学习物理的有力支撑。教师应该研究如何提升习题教学的效率,以更少的题量在精练精讲中让学生获取更高程度的提升,笔者认为变式教学就是一套行之有效的手段。学生在一系列变式问题中,发现隐藏于背后万变不离其宗的分析方法和科学思想,进而提高他们的应变能力和思维能力。以下是笔者围绕变式教学的案例和分析,和大家分享。
The title of the sea tactics often let the exercise of teaching lie, but Needless to say, the exercise is still the strong support for the current students to learn physics. Teachers should study how to improve the efficiency of exercise teaching, with fewer questions to enable students to obtain a higher degree of refinement, I believe that variant teaching is a set of effective means. In a series of variant questions, students find the analytical methods and scientific ideas that are hidden in the ever-changing disciplines and improve their adaptability and thinking ability. The following is the author around the case of variant teaching and analysis, to share with you.
