上海市二期课改后的物理新教材将“匀变速直线运动”放在了第一章.这一章所涉及的物理量特别多,物理关系式也较复杂.不少学生学完这一章后的感受是:教师讲的概念和板演的例题都懂,但自己练习时却对那么多的关系式不知如何入手,使得学生在高中物理入门就对学习产生了畏惧感,以致 The new physical textbooks after the second phase of Shanghai’s curriculum reform put the “uniform linear motion” on the first chapter. This chapter involves a lot of physical quantities, and the physical relationship is also more complicated. Many students learned this chapter. After the feelings are: the teacher’s concepts and examples of board games are understood, but they do not know how to start with so many relationships, so that students in the high school physics to get started with a sense of fear of learning, so that
