习题教学的目的之一是引导学生学习并积累习题解决策略,促使其认知结构(物理情景、概念、规律、方法等)的优化与完善,提高其习题解决能力。习题本身蕴含着丰富的科学方法和物理思想,教学能否达成预期目标,与呈现怎样的习题是休戚相关的。因此,习题的设计无疑承载着十分重要的功能。那么,设计怎样的习题,才能有效挖掘其教学功能呢?实践中,我们从规律掌握、方法习得和提升复习效益三个 The purpose of exercise teaching is to guide students to learn and accumulate exercises to solve strategies to promote their cognitive structure (physical scenarios, concepts, laws, methods, etc.) to optimize and improve their problem-solving skills. Exercises themselves contain a wealth of scientific methods and physical ideas, teaching can achieve the desired goal, and presented what exercises are related. Therefore, the exercise design is undoubtedly carrying a very important function. So, the design of what kind of exercises, in order to effectively tap its teaching function? In practice, we learn from the law, learning methods and improve the effectiveness of review of three
