“机械能”是高中物理学的重要一章,它是学生认识自然界最重要的规律之一——能的转换及守恒规律的启蒙。下面就机械能的教学谈几点认识和体会。一、充分认识能量守恒和转换思想在中学物理学中地位 1、能量的守恒和转换规律的发现,被革命导师恩格斯誉为19世纪自然科学三大发现之一。这一规律也是学生确立辩证唯物主义思想的一个重要基础。 2、从物理教材的内容看其重要性能的守恒及转换思想遍布教材中的力、热、电、光、原子、原子核很多章节。站在能的守恒及转换的思想高度上去学习有关知 “Mechanical energy” is an important chapter in high school physics. It is one of the most important laws that students understand in the natural world - the conversion of energy and the enlightenment of conservation laws. The following points on the understanding of mechanical energy teaching and understanding. 1. Fully recognizing the status of energy conservation and conversion in middle school physics 1. The discovery of the law of conservation and conversion of energy was hailed by revolutionary tutor Engels as one of the three major discoveries of natural science in the 19th century. This law is also an important basis for students to establish the dialectical materialism. 2. From the content of physical textbooks, we look at the conservation and conversion of important performances. There are many chapters in force, heat, electricity, light, atoms and atomic nuclei throughout the textbook. Standing on the conservation of energy and changing the thought height to learn about
