演示实验是物理实验的重要组成部分,但教材为了简化课程,对很多演示实验的解释,常常是笼统地带过,甚至忽视物理定律的限制条件,做出错误解释,极易让学生形成不良的知识观和错误的科学观。本文以教科书中伯努利原理演示实验为例,根据文献,澄清伯努利原理演示实验的原理内涵,倡导正确的物理学习观和教学观。 Demonstration experiment is an important part of physics experiment. However, in order to simplify the course, the teaching materials often explain the many demonstration experiments, and often neglect the limitations of the laws of physics, make mistakes, and make it easy for students to form bad knowledge Viewpoint and wrong view of science. This article takes Bernoulli principle demonstration experiment in textbook as an example, clarifies the principle connotation of Bernoulli principle demonstration experiment according to the literature, and advocates the correct view of physics learning and teaching.
