物理学是一门基础的自然科学,在学习物理的过程中,学生不可避免地会遇到很多的物理公式和物理规律。对于有些物理规律,学生经常会出现一讲就懂,一听就会,一做就错的现象,这是很多高中学生学习物理的一个问题,也是很多高中学生学习物理的困惑。究竟是什么原因造成了学生易懂易会却又易犯错误?我觉得有部分原因是学生遇到了一定的思维障碍,变化率就是学生经常遇到的一个困难问题。学生在变化率问题上常出现错误,笔者分析了出错 Physics is a basic natural science, students in the process of learning physics, students will inevitably encounter a lot of physical formulas and physical laws. For some physical laws, students often speak and understand, listen to and do wrong things. This is a problem that many high school students study in physics. Many high school students also study the physical confusion. What causes students easy to understand but easy to make mistakes? I think part of the reason is that students have encountered some obstacles in thinking, the rate of change is a difficult problem often encountered by students. Students often change the rate of error, I analyzed the error
