中学物理教材中功与能的错误概念解析及讲解策略研究

The Analysis of the “Energy and Function”False Interpretation in Junior School Physics Textbook and the Corresponding Teaching Strategy Study

中学物理教科书中,将实际中背、抱、提、扛、抬着物体运动时,对物体做功的事实释为不做功,忽略了物理力学入门中功能转换的核心内容及动能势能的产生过程分析,本文以人教版八年级物理教材讲解内容为依据,分析诠释中学物理教材中功与能的内容。通过日常生活中实践和实验、观察与感受、思考及例题学习,调整教学讲解策略,系统解释了功和能、功能转换及守恒定律等具体教学内容。

The Junior School Physics textbooks explained the energy was not exist when individuals carry, take, lift, hold and raise the objects, thus neglect the conversion between the energy and function and the analysis of ki- netic energy production. The essay interprets the concepts of energy and function in physics textbook of Renjiao edi- tion used for Grade 8 of middle school. It explains the energy, function, the conversion, the conservation law and the related theories through daily experiences, observation, questioning and exercises.
