每次期末考试,常常看到一些同志,面对自己那不理想的教学效果,感叹自己的教学方法不当,继之是抱怨那不争气的学生。其实,这些同志并没有找到教学效果不好的根本原因。如果他们能细细琢磨一下“要给学生一杯水,自己首先具备一桶水”这句话,或许对他们有点启示。我们先看教者的方法。方法由何而来呢?除了实践、认识、总结、再实践而外,一个人的知识基础则起着决定作用。1+1=2,固然作为任何一个教师都会得出正确答案。可是,如何将这个1+1=2的知识变为学生的能力,我想,如果一个教师仅仅懂得1+1=2,无论如何他是难以胜任的。同理,我们这些中学教师,如果只是具备中学生的文化水平,即使把中学课本背得滚瓜烂熟,在 Every final examination, I often see some comrades in the face of their own unsatisfactory teaching effect, lamented their improper teaching methods, followed by complaining about the disappointing students.
