初中物理教师在引导学生学习苏教版《凸透镜成像规律》这一章节时,普遍觉得让学生掌握这一章节的知识很困难,为了让学生学好这一章节的知识,物理教师们常常伤透了脑筋.这一章节之所以难以让学生理解是由于吸引学生对知识产生兴趣、通过实验让学生了解到复杂的概念、让学生自主的掌握概念这三个环节非常难把握.在这里,我提出一种“凸透镜成像规律”的教学方法,针对这三个重点环节一一攻破.
When junior high school physics teachers are guiding the students to study the “convex lens imaging rule” of the Supian version, it is generally felt that it is very difficult for students to master the knowledge of this chapter. In order to make students learn the knowledge of this chapter, the physics teachers often Hurt the brain.This chapter is difficult to make students understand is due to attract students interested in knowledge through experiments to enable students to understand the concept of complex, so that students can master the concept of these three areas is very difficult to grasp. , I propose a “convex lens imaging ” teaching methods, against the three key areas one by one break.
