在初中物理学习中,有部分学生觉得物理难学,原因之一是怕做物理计算题。怎样才能把计算题做好?我本人有以下几点看法:一、仔细审题在多年的教学工作中,我发现学生普遍存在着理解题意的能力较差、审题不清的问题。如何才能做到审好题,我的理解是:1.理解计算题中的关键词语,挖掘题目中的隐含条件在物理题中,常见的关键用语有:(1)表现为理想化模型的用语,如,光滑,意味着没有摩擦力或者机械能守恒;轻质(杠杆、滑轮)、轻小物体,意味着质量可忽
In junior high school physics study, some students think that physics is hard to learn, one of the reasons is afraid to do physics calculation problem. How can I make the calculation problem? I personally have the following points: First, careful exams In years of teaching, I found that students generally have the ability to understand the inscription is poor, the exam questions unclear. How can we do a good job exam, my understanding is: 1. Comprehend the key words in the calculation questions, mining the implicit conditions in the topic In the physics questions, the common key words are: (1) the performance of the idealized model Terms, such as smooth, mean that there is no friction or mechanical energy conservation; light (levers, pulleys), light objects, means that the mass can be neglected
