在中等學校物理教学中,牛頓运動定律是一個十分重要的課题。通過這個定律的學習,可以使学生明确力的概念和機械運動的基本规律,同時也可以說明在直線運動中物體為什么能作匀迹運動或變速运動。因為這個定律是分散在幾堂課中講授的,學生所得關於這個定律的知識可能很零碎,因此有必要用一堂綜合課來進行系统的複習。下面是我在進行這一工作時的一些體會,介紹出來希望获得同志們的指教。在复習開始時,首先向學生說明複習的主要內容,以及通過這次複習我們對牛頓運动定律将得到什么樣的認識,這樣可以使学生的注
In the secondary school physics teaching, Newton’s law of motion is a very important subject. Through the study of this law, students can make clear the concept of force and the basic law of mechanical movement, and also can explain why the object can make uniform movement or variable-speed movement in linear motion. Because this law is scattered in several lectures taught, the student’s knowledge of the law may be fragmented, so it is necessary to review the system in a comprehensive class. Here are some of my experiences in carrying out this work, introduced in hopes of gaining comrades advice. At the beginning of the review, first explain to the student the main content of the review and, through this review, what kind of understanding Newton’s law of motion will be obtained, so that the student’s note
