论文部分内容阅读
高三物理教学的大部分时间是系统复习,其中几何光学、光的波动性、量子论初步及原子物理这几章在进行单元复习时按以前的教学体验,用常规的讲授复习模式效果不是很好。几何光学的中心内容是反射和折射成像,需要画大量的成像图,占用很多课上时间,从而使课堂容量少,即便将图像提前印在篇子上,也不能显示出其物像变化的动态效果,只能靠老师讲解揭示其内涵,延长了学生理解和掌握的时间,基于以上弊
Most of the third-year physics teaching is a systematic review, in which the geometric optics, the wave of light, the initials of quantum theory, and the atomic physics chapters are used in the review of the previous teaching experience, and the conventional lecture review mode is not very effective. . The center of geometric optics is reflection and refraction imaging, which requires drawing a large number of imaging maps and occupying a lot of class time, so that the classroom capacity is small. Even if the images are printed on the paper in advance, the dynamics of their image changes cannot be displayed. The effect can only be explained by the teacher to reveal its connotation and extend the time for students to understand and master, based on the above disadvantages.
