在济宁市使用沪科版物理新教材备课会上汪延茂、束炳如主编强调新课改下教与学要注重知识与方法,指出物质的比热容这节课非常重要,以前,用旧人教版教材,有的老师为了省事,干脆不做实验,很多老师根据图示,只是定性的分析,学生对这部分知识理解不透彻;而且当时用电加热器加热,也很难控制。本节的重点是通过探究实验认识不同物质有不同的吸热和放热的本领,从而形成比热容的概念,所以落实“探究”过程非常重要。不要过高估计学生的设计能力,老师要为学生的思维做好
In Shanghai Jining City, the use of physical science new textbook lesson preparation Wang Yanmao, Shu Bingru editor emphasizes the new curriculum reform under the teaching and learning should focus on knowledge and methods, pointed out that the specific heat capacity of this lesson is very important, in the past, with the Old Pupils Some teachers in order to save trouble, simply do not experiment, many teachers according to the diagram, just a qualitative analysis, students do not understand this part of the knowledge is not thorough; and was heated with electric heaters, it is difficult to control. The focus of this section is to explore the concept of specific heat capacity by exploring experiments that have different endotherms and exotherms for different substances. Therefore, it is very important to implement the “inquiry” process. Do not overestimate students ’ability to design, and teachers should do well for students’ thinking
