实验探究题是中考物理必考的重要内容,而基本物理量的测量又是其常考内容之一。近年来出现这样一类物理量测量实验设计题,就其理论(或过程)看非常完善,但从技术(或操作)的角度来看,根本无法测量;可以这样讲,这是一类考查学生能力层次比较高的实验设计题;因为完成它,不但要有扎实的实验理论,而且要有较高的技术思想指导,一定的逻辑推理能力和发散性思维。本文试举几例,以给同学们一些启示。 The question of experimental exploration is an important part of the physical examination of senior high school entrance examinations, and the measurement of basic physical quantities is one of the most frequently studied items. In recent years, such a physical quantity measurement experiment design problem appears to be very perfect in terms of its theory (or process), but it can not be measured from the technical (or operational) point of view. It can be said that this is a type of examination of student ability Because of its completion, not only have a solid experimental theory, but also have a higher technical guidance, a certain degree of logical reasoning ability and divergent thinking. This article cites a few examples to give students some inspiration.
