电学计算是初中阶段物理教学的一个难点 ,多数学生即使经过多课时的练习 ,仍不能很好地掌握 .在练习中暴露出学生解题时思维比较单纯 ,不能够做到举一反三来巩固自己所学的知识 .针对这种情况 ,我们设计了一种新的教学方法——“一图多题”.所谓“一图多题”,指在一个不变的电 Electrical calculation is a difficult point in the physics teaching in junior high school. Most students cannot master well even after many hours of practice. It is more simple to expose problems in solving problems in the exercises and cannot consolidate what they learn. In view of this situation, we have designed a new teaching method - “a picture with multiple questions”. The so-called “a picture with multiple questions” refers to a constant electricity.
