一、教材(一)地位、作用和特点本节教材是在学习了光的反射定律等基础知识后,运用光的反射的内容.初中物理对光现象的认识仅限于定性分析(除反射定律外),平面镜成像属知道层次.教材体现了两个特点:其一,展示物理学科的特点——实验科学,体现了用实验手段研究物理的方法;其二,由实验归纳总结结论,符合学生的认知特点.
First, teaching materials (a) status, role and characteristics This section of the teaching material is to learn the light reflection law and other basic knowledge, the use of light reflection content. Junior Physics physical phenomenon is limited to qualitative analysis (except for the law of reflection ), Plane mirror imaging belongs to the level of knowledge. The teaching material embodies two characteristics: First, the characteristics of the physics discipline - experimental science, embodying the method of studying physics with experimental means; Second, summarizing the conclusions from the experiment, in line with the student’s Cognitive features.
