中学物理教学中,根据需要增加一些学生实验的潜力是很大的,这在初中和高中阶段都是可行的,在高中电学教学中我们共增加了三个学生实验,第一个是研究组合电容器的贮电能力,第二个是复习初中物理电学实验,第三个是研究电源的作用以及闭合电路内外电路上的电压降的关系,下面具体地谈一下其中两个增加学生的实验设计思想、目的要求及所用器材。一、研究组合电容器的贮电能力(半课时)高中教材下册第一章静电学中在讲到电容器的组合时,仅从理论上推导出当电容器并联时,组合电容增大,串联时,组合电容减小。这一结论并没有实验的证明,把它列为一个学生
In high school physics teaching, the potential for adding some student experiments is large according to needs. This is feasible in both the junior high school and high school. In the high school electricity teaching we have added three student experiments. The first one is to study the combination capacitor. The second is to review junior high school physical electrical experiments, the third is to study the role of power and the relationship between the voltage drop on the circuit inside and outside the closed circuit, the following specifically talk about two of them increase the student’s experimental design ideas, Purpose requirements and equipment used. First, the study of the storage capacity of the combination capacitor (half the time) High school textbooks The first chapter electrostatic capacitor capacitor combination, only derived from the theory when the capacitors in parallel, the combination of capacitance increases, in series, The combined capacitance decreases. This conclusion is not experimentally proven as a student
