在物理学习过程中,大部分学生最为头疼的知识点莫过于电学原理了。由于这部分内容概念多、规律多、公式多,很多学生虽然能熟背公式,但在实际中解决问题时却不能够灵活运用,有的学生因此对物理学习失去了信心。其实,再难的学习内容只要我们能够掌握其中的方法、技巧、要领,注重练习,善于总结,就能达到“山重水复疑无路,柳暗花明又一村”的境界。这里笔者结合教学实践,谈谈从根本 In the physical learning process, most of the students the most troublesome point of knowledge than the electrical principle. As this part of the concept of content, more rules, more formulas, although many students can familiar with the formula, but in practical problems can not be flexibly applied, and some students therefore lost confidence in physics learning. In fact, as long as we learn the methods, skills, essentials, practice and good summary, we can reach the realm of “no heavy water and no water in the mountains”. Here I combine teaching practice, talk about fundamentally
