心理学认为:练习是学习者对学习任务的重复接触或重复反应,是学生心智技能和动作技能形成的基本途径。所以学习数学如果不进行一定量的练习,就难以牢固地掌握知识,形成熟练的技能、技巧。在过去的课堂上,我们很多老师都对数学练习课不够重视,也不备课,只要把书上的练习做完就了事,其实不然,仔细算算,数学练习课占了整个教学的很大比重。最近两年,我市教研室对练习课提出了新的要求,新的标准:要求我们备好每一节练 Psychology that: practice is a repetitive exposure or repetitive reaction of learners to learning tasks, is the basic way of formation of mental skills and motor skills. So learning mathematics without a certain amount of practice, it is difficult to firmly grasp the knowledge, the formation of skilled skills. In the past class, many of our teachers did not pay enough attention to mathematics practice class, nor did they prepare the class. As long as the practice in the book was done, it was actually not. After careful calculation, the math class accounted for a large amount of teaching proportion. In the recent two years, our city teaching and research room put forward new requirements for the practice class. The new standard requires us to prepare each practice
