一、教学任务分析从新课标的内容与要求来看,对本节内容没有具体要求,一部分教师会选择忽略掉本节内容直接进行功与功率的讲解。但是,追寻和研究守恒量本身是物理学的一种重要研究方法。在实际教学过程中,教师更多地需要教给学生物理思考的方法,本节课内容就可以通过猜想与实验,引导学生找出研究对象是否存在物理量守恒的情况,再总结经验与知识得出守恒定律内容并加以 First, the teaching task analysis From the content and requirements of the new curriculum point of view, there is no specific requirements for this section, part of the teacher will choose to ignore this section directly to the power and power to explain. However, the pursuit and study of conservation quantities are themselves an important research method in physics. In the actual teaching process, teachers need to teach students more physical thinking methods, the content of this lesson can guess and experiment, guide students to find out whether the object of the existence of physical conservation, and then sum up experience and knowledge derived Conservation law and content
