“牛顿第二定律”是通过实验得出的物理学基本规律,教学中做好实验是得出定律的基础.因此,做好实.验对学生理解和掌握本定律至关重要.如果按照常规的方法,教师做实验,在黑板上进行数据处理,得出结论,然后教师进行讲解,这样就很容易搞成“一言堂”,不能实现“学生为主体”的思想.同时,对培养学生的实验操作能力、实验数据的分析能力以及对实验的科学态度都不利.于是在授课时我们大胆采用现代教学媒体,进行了如下尝试. “Newton’s second law” is the basic law of physics obtained through experimentation. Good experimenting in teaching is the basis for drawing the law. Therefore, it is very important for students to understand and master this law. In the method, the teacher conducts experiments, conducts data processing on the blackboard, draws conclusions, and then the teacher explains, so that it is very easy to create a “learning hall” and not to realize the “student-centered” thinking. At the same time, the students’ experiments The ability to operate, the analytical power of experimental data, and the scientific attitude to the experiment were all unfavorable. Therefore, we boldly adopted modern teaching media during the lectures and conducted the following experiments.
