一道好题的价值之一在于它能产生其他一些好题.——波利亚波利亚曾说过:“如果你想学会游泳,你必须下水;如果想成为解题能手,你必须解题.”因此数学教学离不开学生的解题,而且让学生做得既对又快也是每一位数学教师的梦想.但是作为数学教师,如果奉行时间换质量的原则,迫使学生加班加点来实施题海战术,从表面现象上看,他们的短期学习效果应该不错,但囫囵吞枣、重复训练的结果与教师的预想往往是大相径庭.
One of the good values of a good question is that it produces other good things .-- Polyana said: “If you want to learn to swim, you have to go off the water. If you want to be a problem solver, you have to solve it Question. ”Therefore, mathematics teaching can not be separated from the student’s problem solving, but also make the students do it both fast and every math teacher’s dream.But as a math teacher, if the principle of time for quality, forcing students to work overtime To implement the sea tactics, from a superficial point of view, their short-term learning should be good, but the results of repeated training are often very different from the teachers’ expectations.
