很多教师在初三电学部分的复习中发现部分同学学得太枯燥,虽然掌握了很多电学知识,会做很多电学题目,但总觉得课本中出现的灯泡、电阻、电热器等离生活太远。学生既怕动手也不会动手,在电学的教学中虽然有“欧姆定律”“伏安法测电阻”“测电功率”等实验,但学生在动手时接触的都是实验室里的器材,且是按课本要求进行实验,没有生活中的情景,学生缺乏兴趣,为了实验而实验。教材中有一个综合实践活动:利用家庭电路中的电 Many teachers found that some of their classmates were too boring to review the electrical part of the third grade. Although they had mastered a lot of electrical knowledge and would do many electrical topics, they always felt that the light bulbs, resistors and electric heaters that appeared in the textbooks were too far away from life. Students are afraid of hands-on and hands-on. Although there are experiments such as “Ohm’s Law”, “Voltammetric Resistance Measurement” and “Measuring Electric Power” in the teaching of electricity, students are exposed to experiment Room equipment, and is based on the textbook requirements of the experiment, there is no life scene, the students lack of interest in order to experiment and experiment. There is a comprehensive practice in teaching materials: the use of electricity in the home circuit
