应該首先說明,我們在這里並不打算就這一課題的教學方法作一全面的系統的叙述,而只是就其中幾個重要的問題提出我們的意見,供同志們教學中的參考。 1.在由“直線運動”轉入這一課題的時候,教師应該告訴学生,在直線運動中我們所研究的是物體在怎樣運動着的問題,显然,我們很自然地要問,物體為什么会作勻速或變速運動呢?牛頓運動定律回答了這個極其重要的問題,因此我們现在就來學習牛頓運動定律。
First of all, we should make it clear that we are not going here to make a comprehensive and systematic account of the teaching methods of this subject. Instead, we are just presenting our opinions on several important issues for our reference in teaching. 1. In moving from “linear motion” to the subject, teachers should tell students that in straight-line motion we are studying the problem of how an object is moving. Obviously, it is natural to ask why an object Will it move at a constant or variable speed? Newton’s law of motion answers this extremely important question, so let’s learn Newton’s law of motion now.
