物理概念的教学有它特殊的教学规律和程序。下面我以初三物理“比热”一节课为例,谈谈我对概念课教学法的探讨。 “比热”是定量地反映物质吸(放)热本领的物理量,是热学部分的重要概念之一。根据中学物理教学大纲的要求,本节教学目的是:1.使学生理解并掌握比热的概念和单位;2.知道比热是物质的一个重要特性;3.了解比热在生产实际中的应用。我采用了下面的教学程序: 一、新问题的提出——设疑建立新概念之前,有意识地、有针对性的复习与新概念有关联的旧概念,以导出急待解决的新问题非常必要,只有这样,才能有利于打开
The teaching of physical concepts has its special teaching laws and procedures. Below, I took the class of Physics 3 in the third year as an example to discuss my concept teaching method. “Specific heat” is a physical quantity that quantitatively reflects the ability of a substance to absorb (discharge) heat. It is one of the important concepts in the thermal sciences. According to the requirements of the physics syllabus for middle schools, the purpose of this lesson is to: 1. Make students understand and master the concepts and units of specific heat; 2. Know that specific heat is an important characteristic of matter; 3. Understand the specific heat in the actual production. application. I have adopted the following teaching procedures: First, the introduction of new problems - before the establishment of new concepts, consciously, targeted review of the old concept associated with the new concept, in order to derive new issues that are urgent to be solved is very necessary Only in this way can it be helpful to open
