欧姆定律这部分教学中涉及了许多科学探究和实践活动,学生需要经过对实验结果的分析归纳,得出规律,再应用这个规律研究解决电路中的问题。实验题是最能体现物理学习能力的一种题型,它不仅能反映学生学习过程中的观察能力、动手动脑能力,而且还能反映学生对学习的物理概念和物理规律的理解情况。复习要加大实验技能的提高,近几年中考中物理题中实验题的数量及分值呈上升趋势,掌握
Ohm’s Law This part of the teaching involves a lot of scientific inquiry and practice activities, students need to analyze the results of the experiment summarized, come to the law, and then apply this law to solve the problems in the circuit. Experimental questions are the most typical questions that can reflect the ability of physical learning. They not only reflect students’ ability of observation and brain activity, but also reflect their understanding of the physical concepts and laws of learning. Review to increase the improvement of experimental skills, in recent years, the number of physical examination questions in the middle school exams and the score is on the rise, grasp
