凸透镜成像是初中物理教学过程中的一个教学任务,该节内容具有抽象、难度大的特点。虽然凸透镜在生活中受到广泛应用,但对于初中生来说,理解起来也有一定的难度。本文结合实际教学经验,简要阐述如何合理引导学生掌握凸透镜成像规律,从而提高教学效率。初中物理教学主要采用实验教学的方式,使学生在亲自实践中,掌握有关的物理知识。实验的方式,有利于学生更加直观地发现物理中存在的变化。就凸透镜的成像规律而言,教师在教学中主要采用实验的方式,引导学生仔细
Convex lens imaging is a teaching task in the physics teaching process of junior middle school. The content of this section is abstract and difficult. Although the convex lens is widely used in life, it is also difficult for junior high school students to understand. This article combines practical teaching experience to briefly explain how to reasonably guide students to master the law of convex lens imaging so as to improve teaching efficiency. The junior high school physics teaching mainly uses the experimental teaching method, so that the students can master the relevant physical knowledge in personal practice. The experimental approach helps students more intuitively discover changes in physics. As far as the imaging law of convex lenses is concerned, teachers mainly use experimental methods in teaching to guide students to carefully
