物理教学必须以实验为基础,特别在初中物理教学中,更要突出实验的基础作用。即通过实验教学培养学生学习物理的浓厚兴趣;在实验提供的充分的感性认识的基础上,建立物理概念和认识物理规律,培养学生的能力和养成良好的习惯。要达到上述要求,必须要有教师的示范、引导和学生的亲自实践,二者缺一不可。其中教师的演示实验是引导和示范的有效方法。本讲将着重介绍怎样做好演
Physics teaching must be experiment-based, especially in junior high school physics teaching, but also to highlight the experimental basis. That is to say, students should be encouraged to learn physics through experimental teaching. On the basis of adequate perceptual knowledge provided by experiments, physical concepts and physical laws should be established so as to cultivate students' abilities and develop good habits. To achieve the above requirements, teachers must demonstrate, guide and practice students themselves, both indispensable. The teacher's demonstration experiment is an effective way to guide and demonstrate. This talk will focus on how to do a good show
