3.習題解答解答習題是物理教學的重要的和有效的方法。然而它不是教学的目的。解答習題可以使學生更好地掌握物理知識。它能幫助形成基本的物理概念,幫助理解物理規律,幫助建立所學的各現象间的聯系,幫助學生把在對於物理的各部分所學的知識融會貫通。在很多情形下,習題能够暴露教師在講述教材中沒有闡明的物理現象的某些問题。
3. Exercise Answer Solution Exercise is an important and effective method of physics teaching. However, it is not for teaching purposes. Answer exercises can make students better grasp of physical knowledge. It helps to form the basic concepts of physics, to help understand the laws of physics, to help establish the connections among the phenomena that are learned, and to help students to integrate the knowledge learned in the various parts of physics. In many cases, the exercises expose some of the questions the teacher is telling about physical phenomena not covered in the textbook.
