实验,是自然科学研究的重要方法,也是自然学科教学的重要手段,实验能力是高考物理学科要考核的五个能力之一。因此,搞好高中物理实验的复习,摸清实验中的研究方法是至关重要的,教学中,我总结了以下五条实验中的研究方法。1、理想化法:影响物理现象的因素往往复杂多变,实验中常可采用忽略某些次要因素或假设一些理想条件的办法,以突出现象的本质因素,便于深入研究,从而取得实际情况下合理的近似结果(通俗他说就是抓大放
Experiment, is an important method of natural science research, but also an important means of natural subject teaching, experimental ability is one of the five competencies of college entrance examination physics subject. Therefore, it is very important to do a good review of high school physics experiment and find out the research methods in experiment. In teaching, I summarize the research methods in the following five experiments. 1, the idealization method: the factors that affect the physical phenomena are often complex and changeable, the experiment can often ignore the use of some minor factors or assume some ideal conditions in order to highlight the essence of the phenomenon, to facilitate in-depth study to obtain the actual situation Reasonable approximation (popular, he said is a big release
