在教学过程中,凸透镜成像的规律是让学生在课堂上的探究,通过在全过程中的独立性、主动性,通过学生认真观察与思考,最后自己形成清晰的凸透镜成像的规律.在教学目标的要求中,凸透镜成像的规律属于“知道”的水平,要求并不高,如果学生只知道像的大小、正倒、虚实也就达到了标准的要求.但在实际教学中我发现学生仅仅知道像的大小、正倒、虚实是远远不够的.学生不但要在头脑中清晰的知道凸透镜成像的规律,而且要对凸透镜成像规律会灵活运用.
In the teaching process, the law of convex lens imaging is to allow students to explore the classroom, through the entire process of independence, initiative, through careful observation and reflection of students, and finally form a clear law of convex lens imaging in the teaching objectives Of the requirements, the law of convex lens imaging belongs to “know ” level, the requirement is not high, if the students only know the size of the image, down, the actual situation has reached the standard requirements.But in the actual teaching I found that students Just know the size, is down, the actual situation is not enough.Students should not only know clearly in the mind the law of convex lens imaging, but also to lenticular imaging laws will be flexible use.
