初中物理教学重点是从实际生活出发,对发生在我们身边的物理现象进行讲解,从而降低学生理解知识的难度,使他们对物理学这门基础性的自然科学有初步的了解。本文以初中物理摩擦力知识点为具体教学案例,结合“实践与总结”的教学方法,归纳整理了初中物理教学中的规律,以期为学生后续的学习奠定坚实的基础。 The focus of junior high school physics teaching is to explain the physical phenomena that occur in our side from the actual life, so as to reduce the difficulty of students’ understanding of knowledge and make them have a preliminary understanding of the basic science of physics. In this paper, the junior middle school physics knowledge of friction as a specific case teaching, combined with “practice and summary ” teaching methods, summarized the laws of junior high school physics teaching, in order to lay a solid foundation for the students follow-up study.
