物理学是以实验为基础的科学.物理实验能具体形象地展示物理知识的形成过程,为学生的学习提供丰富的感性材料,强化学生的感知或者纠正学生感知中的错觉,是学生发现物理现象、探究物理规律、获取物理知识、提升科学素养的重要途径.但是教材中的部分实验演示效果不够明显,探究实验过于复杂或者由于实验条件的限制,很多重要的实验无法完成,严重影响了教学效果.要改变这种现状,可以从以下几方面进行.
Physics is experiment-based science.Physical experiments can show the forming process of physical knowledge in concrete form, provide rich sensory materials for students’ learning, strengthen students’ perceptions or correct the illusion of students’ perceptions, so that students can discover physical phenomena , To explore the laws of physics, access to physical knowledge, improve scientific literacy an important way.But some of the teaching materials in the demonstration of the effect is not obvious enough, the inquiry experiment is too complicated or due to experimental conditions, many important experiments can not be completed, seriously affecting the teaching effectiveness To change this situation, we can proceed from the following aspects.
