液体压强公式p=ρgh形式虽简,但学生在理解、掌握以及应用方面,常常是不尽人意,究其原因,与教师在教学方法上没有突破教材给我们划定的框框有关。而受教材本身的内容所束缚。事实上,对本节内容的教学方法作适当改进,是能收到较好效果的。下面谈谈自己的看法和做法。一、教材内容简评现行初中物理教材(1987年5月第二版),液体压强公式是通过计算圆筒形容器
Although the liquid pressure formula p=ρgh is simple, the students are often unsatisfactory in understanding, mastering, and applying. The reason for this is that the teacher did not break through the teaching materials to give us a definite frame. It is bound by the content of the textbook itself. In fact, the proper improvement of the teaching methods in this section is to receive better results. Let’s talk about our own opinions and practices. I. A brief review of the current textbook content of the junior middle school physics textbook (second edition, May 1987). The liquid pressure formula is calculated by counting cylindrical containers.
