数学基本活动经验,即在教学目标的指引下,通过对具体事物进行实际地、数学化地观察、操作和思考,形成和积累的过程性知识。荷兰数学教育家弗赖登塔尔说:“数学学习是一种活动,这种活动与游泳、骑自行车一样,不经过亲身体验,仅仅从看书本、听讲解、观察他人的演示是学不会的。”可见,数学教学要关注学生基本活动经验的积累。笔者认为,有效的数学课堂教学要留出充分的时间和
The basic activities of mathematics experience, that is, under the guidance of the teaching objectives, through the actual, mathematical observation, operation and thinking of specific things, the formation and accumulation of process knowledge. Dutch mathematics educator Freudenthal said: “Mathematics learning is an activity that, like swimming and cycling, does not go through personal experience, just reading a book, listening to explain, observing the demonstration of others is not learning Will. ”Visible, mathematics teaching should pay attention to the accumulation of students’ basic activities experience. The author believes that effective mathematics classroom teaching should set aside sufficient time and
