初中物理中的大多知识点是建立在实验基础之上的,实验完成的好与坏决定了物理知识掌握的程度,甚至影响整个知识体系的学习.著名教育家凯洛夫指出:在教学过程中首先要遵循学生的自觉性与积极性原则和教学的直观性原则;同样根据初中学生形象思维居主导、抽象思维尚处于发展中的心理特点及物理学习探究性强的角度来看,实验是否简单易行、是否能够让学生有所启发,是能否高效教学的关键.所以我们要力争“用最简单实验,创最高效课堂.”当
Most of the junior high school physics knowledge is based on the experiment, the completion of the experiment is good or bad determines the degree of grasp of physical knowledge, and even affect the entire knowledge system learning.Keloff, a famous educator pointed out: in the teaching process First of all, students should follow the principle of self-awareness and enthusiasm and the principle of teaching intuitive; the same under the guidance of junior high school students in the image of thinking, abstract thinking is still in the development of the psychological characteristics and physical learning to explore strong point of view, whether the experiment is simple and easy Whether we can inspire students or not is the key to effective teaching, so we must strive to create the most efficient classroom with the simplest experiments.
