新授课中学生已经掌握了牛顿第一定律的内容,并且在后续学习中巩固了这一定律。复习课中我设计了一组习题,让学生体会:物理前辈不仅给后代留下了宝贵的结论,更重要的是留下了奇特的思维方法———极端法。学生在解题过程中,达到知识的掌握、方法的传授、能力的培养融为一体的目 Newly taught middle school students have mastered the content of Newton’s first law, and have consolidated this law in subsequent learning. During the review class, I designed a set of exercises to let students understand that physical predecessors not only left valuable conclusions for future generations, but more importantly left a strange way of thinking—extreme methods. In the process of solving problems, students achieve the goal of mastering knowledge, imparting methods, and cultivating competence.
