一、引入生活中、现实中存在的关于动量守恒定理的实例,引导学生思考,增强学生的求知欲望对培训学员采用发问式教学方式,所有物理中的现象都是源于现实生活中存在的真实事物,有的则是对物理科学的成功应用,利用动量守恒定理在当今社会发展中的实际应用进行教学,在新课开始前能够将这些活生生的例子展现给同学,利用多媒体等先进设备让学生直观地感受到这些物理现象的存在,然后对学生进行发问:为什么会出现这样的现象,这种现象中哪些与我们要研究的内容有关,我们应 First, the introduction of life, the reality of the existence of the law of conservation of momentum examples to guide students to think and enhance students’ desire for knowledge of trainees using question-based teaching, all the phenomena in the physical are derived from the reality of real life Things, and others are the successful application of physical science, the use of conservation of momentum theory in today’s social development of the practical application of teaching, in the new class before the start of these live examples can be demonstrated to the students, the use of multimedia and other advanced equipment for students Intuitively feel the existence of these physical phenomena, and then ask questions to students: Why is there such a phenomenon, which phenomenon is related to what we want to study, we should
