物理学是一门以实验为基础的学科,在物理课堂教学设计中,教师要针对学生的疑难、困惑,想方设法设计好实验,帮助学生深刻理解物理规律的本质,激发学生学习的兴趣。本文以《电容器的电容》为例,在实验为基础上,进行课堂教学设计,突出重点,突破难点,从而达到提高课堂教学有效性的目的。 Physics is an experiment-based discipline. In the design of physics classroom teaching, teachers should try their best to design experiments according to the students’ difficulties and confusion, help students to understand the essence of the laws of physics and stimulate their interest in learning. In this paper, the “capacitor capacitance” as an example, based on the experiment, the classroom teaching design, highlighting key points, breaking the difficulties, so as to achieve the purpose of improving classroom teaching effectiveness.
