大气压强是初中物理的学习难点,概念较为抽象,学生不容易理解。教学中如果只用多媒体课件来演示和讲解大气压强,学生没有切身感受,就很难利用其原理来解释日常生活中有关的现象,因此在“大气压强”中的实验教学特别重要。本文是笔者对“大气压强”实验教学的探索与体会。 Atmospheric pressure is the junior high school physics difficult to learn, the concept is more abstract, students are not easy to understand. If only multimedia courseware is used to demonstrate and explain atmospheric pressure in teaching, if students have no personal experience, it is very difficult to use their principles to explain the phenomena in daily life. Therefore, experimental teaching in “Atmospheric Pressure” is particularly important. This article is the author of “atmospheric pressure ” experimental teaching exploration and experience.
