物理学科有着严谨的体系、紧密的结构和极强的科学性,同时十分强调操作性,许多理论的理解与运用需要学生亲自动手探究才能得以达成.初中物理的内容主要是力学、光学和声学的基础知识,与高中物理相比,更容易让学生将之与常见的生活现象相联系,计算相对简单;它的任务应当是激起学生对自然与科学的好奇和兴趣.因此,初中物理课堂的各个环节的安排设置,除了要考虑围绕主要授课点外,还应当尽量以激发和保护学生的探索欲为基本出发点.课堂导入作为教学环节的 Physics has a rigorous system, close structure and strong science, while emphasizing operability, many of the theoretical understanding and use of students need to explore in order to be able to achieve. The content of junior high school physics is mainly mechanical, optical and acoustic The basics, compared with high school physics, make it easier for students to relate them to common life phenomena and the calculation is relatively simple; its task should be to arouse students’ curiosity and interest in nature and science. Arrangements in all aspects of the arrangement, in addition to consider the main teaching around, but also should try to inspire and protect the exploration of students as the basic starting point.
