压力的概念在初中物理教学中占有很重要的位置.在新修订的教学大纲中对“压力”的教学要求是:知道压力的概念.原来的教学要求是:理解压力的概念.看来,新修订的大纲对“压力”的教学要求降低了.为什么降低了,我认为可能是教学中感到学生学起来困难了,不好接受了,出的错太多了等.压力的概念,真的那么抽象难懂吗?我认为不尽其然.我们知道,在教材中,压力的概念是在第十章压强、液体压强的第一节压力和压强中介绍的,明确指出:物理学 The concept of stress occupies a very important position in physics teaching in junior middle schools. The teaching requirement for “stress” in the newly revised syllabus is: to know the concept of stress. The original teaching requirement is: to understand the concept of stress. It seems that The newly revised outline has reduced the teaching requirements for “stress”. Why is it reduced?
