过去,在講授高二物理学“水流的能的利用”时,由于对贯彻理論联系实际的重要性不够明确,因而,这一教材沒有引起我们的注意,在教学中,总是把它摆在次要的地位,講解时就一笔带过。这充分說明了过去物理教学中所存在的缺点;同时,也反映出我们思想上的不正确看法,只重視物理知識的灌輸,而忽 In the past, when teaching “the utilization of the water flow” in sophomore physics, because of the lack of clarity on the importance of implementing theory with practice, the textbook did not attract our attention. In teaching, To the status of a time to explain. This fully shows the shortcomings of the past physical teaching; the same time, it also reflects our thoughts on the incorrect view, only emphasizes the inculcation of physical knowledge, and suddenly
