初中物理课安排了很多学生实验课,研究实验课的最优化问题是初中物理教学的重要改革,因为学生实验课完成的如何直接影响物理教学质量。最近我们物理教师研讨班作了一节关于研究杠杆平衡条件的实验课,在改进学生实验课的课堂教学结构方面进行了尝试并有所突破,且受到老师们的好评。本节课突出的特
The junior high school physics class has arranged a lot of student’s experiment classes, the optimization problem of studying the experiment class is the important reform of the junior middle school physics teaching, because how does the student experiment class finish directly influence the physics teaching quality. Recently, our physics teacher seminar made a section of the experimental class on the study of lever balance conditions. It tried to improve the classroom teaching structure of students’ experimental class and made breakthroughs. It was well received by teachers. The highlights of this lesson
