物理教学必须以实验为基础，这已经成为广大物理教师的共识．近几年来，我们的物理教育者，在加强实验教学，改进实验方法，自制教具等方面取得不少的成绩，但是，在学生实验教学中，仍存在许多问题，其中实验原理指导是薄弱环节之一，本文结合教学实际，对实验原理教学模式作 Physics teaching must be based on experiments, which has become the consensus of the majority of physics teachers. In recent years, our physics educators have scored many achievements in strengthening experimental teaching, improving experimental methods, and self-made teaching aids. However, there are still many problems in students’ experimental teaching. Among them, the guidance of experimental principles is the weak link. First, this article combines teaching practice and the experimental teaching model
