对中学物理“超重失重”教学的几点思考

Several Thoughts on Overweight and Weightlessnessin High School Physics

超重与失重不仅是牛顿第二定律的典型应用,对培养学生的类比等效等科学思维能力也有独特价值.从超重与失重概念引入、教学意义、思维价值、典型案例选取等方面探讨超重与失重问题在高中物理教学中的地位和作用.

Overweight and weightlessness are not only the typical application of Newton′s second Law,but also have unique value in training students′scientific thinking ability such as analogy and equivalence.The paper discusses the status and function of overweight and weightlessness in high school physics teaching from the aspects of concept introduction,teaching significance,thinking value and selection of typical cases.
