好多同学对于高中物理的感受是:听听简单做题难、规律简单应用难.究其原因,关键是分析问题时抓不住要害,而一旦老师指点出来,则立马感到简单,因而他们的症结在于寻找不到解题的角度.物理问题本是物理规律的应用题,只有努力培养起学生在这方面的感悟,学会如何去寻找角度(题目称为抓手),方能提高他们应用知识分析问题和解决问题的能力.本文以平抛运动为例,浅谈一下如何去寻找平抛运动问题的抓手,突破难点,提升解题能力.
A lot of students’ feelings about high school physics are: It’s hard to listen to and listen to questions, and it’s difficult to apply the rules. The reason is that the key is to analyze the problems and not grasp the key points. Once the teacher points out, it is easy to find out, so their crux. It is in the perspective of not finding a problem. The physics problem is the application of the laws of physics. Only by striving to develop students’ perceptions in this respect, and learning how to find the angle (the subject is called the grasper) can improve their application knowledge analysis. Problems and ability to solve problems. This article takes Ping throwing sports as an example, discusses how to find the handle of Ping throwing sports problems, break through the difficulties and improve the ability to solve problems.
