“探究凸透镜成像的规律”是八年级物理第四章第三节的教学内容,是初中物理中较难的探究实验之一。要使学生较好地完成该实验探究,关键是器材的选择是否有利于学生的探究。若按教材所述方案让学生去探究凸透镜成像的规律,则学生是得不出一个 “Probing the law of convex lens imaging ” is the teaching content of the fourth quarter of the eighth grade physics, is one of the more difficult exploration experiments in junior middle school physics. For the students to complete the experiment to explore, the key is the choice of equipment is conducive to student inquiry. If the program described in the textbook allows students to explore the law of convex lens imaging, the students can not get a
