物理是一门以观察实验为基础的学科,因此物理教学也必然以实验为基础.实践证明:课堂实验活动能为学生学习物理知识提供感性的认识,帮助其形成表象,突破学习中的难点.学习物理的过程中,形成物理概念和物理规律,必须有一定的感性认识.加强实验教学,既可以激发学生的学习兴趣,还可以培养学生较强的动手操作能力.实验教学固然重要,可是不少教师都在问,该如何开展实验教学呢?笔者结合自己的教学实践,就初中物理实验有效性教学,谈谈自己的看法.一、创设教学情境,引发实验热情初中物理实验富有趣味性,教师应通过物理实验的趣味性 Physics is a subject based on observation experiment, so physics teaching must also be based on experiments.It has been proved by practice that classroom experiment activities can provide students with a sense of perceptual knowledge of physical knowledge, help them form an appearance and break through the difficulties in learning. In the course of studying physics, the formation of physical concepts and laws of physics must have some perceptual knowledge.Improve the experimental teaching can not only stimulate the students ’interest in learning, but also cultivate students’ strong hands-on ability.Experimental teaching is important, but not Less teachers are asking, how to carry out experimental teaching? The author combined his teaching practice, the effectiveness of junior high school physics experiment teaching, to talk about their own views. First, create a teaching situation, triggering enthusiasm for the experiment of physics experiments in junior high school is full of fun, Teachers should go through the fun of physics experiments
