新课引入的方法很多,各有特色,本文里笔者就“设计法”在新课引入中的应用,谈谈自己粗浅的看法。一、“设计实验”法引入观察和实验是物理学研究的基本方法,在中学物理教学中,它们是学生获得感性认识的基本途径,也是形成、发展和检验物理概念、物理定律的基础.在引入新课时,可以根据新课教学的内容,有目的、有针对性的设计一些小实验,学生通过实验,提高观察能力和实验能力,激发了学习的兴趣。例如:在引入“大气压强” There are many methods introduced in the new class, each with its own characteristics. In this article, the author discusses the application of the “Design Law” in the introduction of new lessons and talks about his own superficial views. First, the “design experiment” method introduces observation and experimentation as the basic methods of physics research. In the middle school physics teaching, they are the basic way for students to gain perceptual knowledge, and they are also the basis for the formation, development, and examination of physical concepts and physical laws. When introducing new classes, according to the content of the new class teaching, some small experiments can be designed with purpose and pertinence. Students can improve their observation ability and experimental ability through experiments, and stimulate their interest in learning. For example: The introduction of “atmospheric pressure”
