初中物理电学部分,电路是教学的重点,而“短路”问题又是电路中的一个难点。由于初中学生在这方面实际接触较少,因而在“短路”教学中,我采取了“以实验引出概念”、“用形象的比喻诠释概念”、“画直观的电路图辩析概念”、“做习题来强化概念”的方法,让学生循序渐进逐步理解。下面就教学中的做法写出体会点滴,供参考。 In the junior high school physics department, the circuit is the focus of teaching, and the short circuit problem is a difficult point in the circuit. Due to the fact that junior high school students have few practical contacts in this area, in the “short-circuit” teaching, I have adopted the concept of “extracting ideas by experiment”, “interpreting concepts using metaphors of images”, and drawing “intuitive circuit diagrams.” Analyze concepts “,” and do exercises to reinforce the concept ", so that students can gradually understand. The following writes about experiences and practices in teaching for reference.
