按常理说应该是种瓜的学种瓜,卖菜的学卖菜。教什么课钻研什么科学。可是生活中偏偏有怪事。教物理的老师专门学数学。有位教师总结自己的教学经验说:他为了搞好物理教学,专门听本校老师讲解析几何,而且几乎把高中数学全复习了一遍。这是不是不务正业呢?否。现在这位物理老师通过数理的综合运用,改进了物理教学,一道力学题,在课堂上他可以引导同学们用做图法,几何的相似三角形法,代数的解析法,三角函数法等方法去解。这样可以使学生融会贯通地掌握知识,大大提高学生分析问题和解决问题的能力。教什么应该精于什么,但仅仅懂得自己所教学科,而对有关学科的知识一窍不通或知之甚少,要想 According to common sense, it should be a kind of melon to learn to plant melons and sell vegetables to sell vegetables. What lessons are taught in what science. However, there are strange things in life. Teachers who teach physics specialize in mathematics. One teacher summed up his teaching experience and said: In order to do a good job in physics teaching, he specifically listened to the school’s teachers to explain analytic geometry, and he almost completely reviewed the high school mathematics. Is this not a bad job? No. Now the physics teacher has improved the physics teaching through a comprehensive application of mathematics and physics. In a class, he can guide the students to use diagrams, geometric similar triangles, algebraic analysis, trigonometric methods, etc. solution. This will enable students to master knowledge and improve their ability to analyze problems and solve problems. What should be taught what to be good at, but only know how to teach it, and know nothing about the subject or know little about it.
