实验探究是物理核心素养的重要组成部分,物理实验又是学生能够高度参与的教学载体.在实验教学的二次开发中,一方面,我们应设计更多的空间、时间能够让学生参与进来;另一方面,在实验中,我们应让实验更有展示性、可操作性、本真性,这样才能充分激发学生学习的热情;同时,结合课堂时间的有效性,实验应具有易操作,易成功的特点.笔者作为一线教师,在人教版选修3-1的“静电现象的应用”一课的教学过程中,课文中的演示实验在实际操作中碰到很多困难,基于此,笔者结合自己的教学需求与点滴经验提出了自我的一点看法,并制作了一个静电现象演示仪.
Experimental exploration is an important part of physical core literacy, and physics experiment is also a teaching carrier for students to be highly involved in. In the secondary development of experimental teaching, on the one hand, we should design more space and time to let students participate; On the other hand, in the experiment, we should make the experiment more demonstrative, operable and authentic, in order to fully stimulate the enthusiasm of students’ learning. At the same time, in combination with the validity of the classroom time, the experiment should be easy to operate and easy to be successful Of the characteristics of the author as a front-line teacher in the PEP 3-1 optional “electrostatic phenomenon of the application of ” a lesson in the teaching process, the demonstration of the text in the actual operation encountered many difficulties, based on this, the author Combined with their own teaching needs and bit by bit experience put forward a little self-perspective, and produced a static phenomenon demonstrator.
