物理是一门以观察和实验为基础的学科,很多知识都可以直接从实验中得出.推行新课程标准以来.教师对实验教学更加重视,它不仅能培养学生科学的思维方法,还能培养学生动手能力,促进学生综合素质的提高.所以我在教学中常常用实验来解决一些学生不易理解的问题.情景1学习了欧姆定律后分析电路中电流、电压变化情况时,不少同学对于图1中滑片移动时电流表和电压表示数变化的情况会分析,但对于图2及图3的分析就是不很清楚了.通
Physics is a subject based on observation and experiment, a lot of knowledge can be directly drawn from the experiment.Since the implementation of the new curriculum standard, teachers attach more importance to experimental teaching, which not only can train students’ scientific thinking method, but also cultivate Students ability to improve the overall quality of students, so I often used in teaching experiments to solve some of the problems students are not easy to understand Scenario 1 Ohm’s law to learn the analysis of current and voltage changes in the circuit, many students on the map 1 in the slide when the ammeter and voltage changes in the expression of the situation will be analyzed, but the analysis of Figure 2 and Figure 3 is not very clear.
