几何光学中的动态问题,是光学教学中的难点,采用传统的教学手段和方法,难以适应新形势下物理教学的要求;笔者借助于几何画板,通过构建动态光学问题的情景,引导学生观察思考、发现问题、猜想探究、分析论证……,取得了较为满意的教学效果。 The dynamic problem in geometrical optics is a difficult point in optical teaching. It is difficult to adapt to the requirements of physics teaching in the new situation by using traditional teaching methods and methods. By means of geometrical drawing board, the author guides students to observe and think by constructing scenes of dynamic optics problems , Found the problem, conjecture to explore, analyze and prove ..., has made a more satisfactory teaching effect.
