“听会忘记,看能记住,只有做才能理解。”建构主义学者倡导的以“动手做”为核心的“做中学”教学理念,为教育教学注入了活力。数学概念作为数学大厦的基石,其形成是一个从具体到抽象的归纳、概括过程。概念教学不是简单的赠与,而是一个探究的过程。概念的获得必须依靠学生的自主探究,实施有意义的建构。笔者在多年的数学教学中始终秉承“闻之不如见之,见之不如亲历之”的教学原则,组织学生在做中学概念。现以苏教版《数学》六年级上册“体积的意义”一课教学为 “Listening will forget, look to remember, only to do to understand. ” Constructivism scholars advocate “do it by hand” as the core “do secondary” teaching philosophy, for the education and teaching into the vitality. Mathematical concept as the cornerstone of math building, its formation is a concrete to abstract induction, generalization process. Concept teaching is not a simple gift, but a process of inquiry. The concept of access must rely on the students to explore their own, the implementation of meaningful construction. The author in many years of mathematics teaching has always been adhering to the “smell is better to see it, see the calendar ” teaching principle, organize students to do the concept of high school. Now in the Soviet version of “Mathematics” sixth grade on the volume of “the meaning of volume” a lesson for
