老师教,不只是让学生学会知识,更重要的是让学生学会学习方法.著名数学家华罗庚先生在谈及数学研究时,提到四种境界:一是依葫芦画瓢地模仿;二是利用现成的方法解决新问题;三是提出新的思路,创造新的方法;四是开辟新的研究领域,这是学习数学的精髓.如果把这种境界用在平时的数学教学中就是四轮渐近教学法,即一轮课堂模仿、二轮作业独立解决、三轮小组研讨、四轮自学升华.本文就此进行探讨.
Teachers teach, not only to enable students to learn knowledge, more importantly, to enable students to learn the method of learning famous mathematician Mr. Hua Luogeng talked about mathematical research, referred to four realms: First, according to gourd scrawl to imitate; the second is to use Ready-made methods to solve new problems; third is to put forward new ideas and create new methods; Fourth, open up new areas of study, which is the essence of learning mathematics .If this state of mind in the usual mathematics teaching is a gradual Near teaching method, that is, a classroom imitation, two separate homework, three rounds of group discussions, four self-study sublimation .This article discusses.
