课堂上的高效低耗是目前大家所追求的一种教学理念和教学实践,因为它能够最大化达成课堂教学目标的同时降低师生的消耗。因此,在课堂教学中,如何实现初中物理的高效低耗就成为一个很有意义的课题。通过实践“四段法教学”能在初中物理课堂上实现高效低耗。 The high efficiency and low consumption in the classroom is a kind of teaching idea and teaching practice that everybody pursues at present, because it can reach the classroom teaching goal and reduce the consumption of teachers and students at the same time. Therefore, in classroom teaching, how to realize the high efficiency and low consumption of junior middle school physics becomes a very meaningful topic. Through the practice of “four-step teaching” can be achieved in junior high school physics classroom efficient and low consumption.
