在数学教材中,数学知识的呈现是先浅后深逐级递进。这体现了知识由浅入深、由易到难的渐进发展理念,也符合儿童由直观到抽象、简单到复杂的认知规律。教材是呈现数学知识的主要载体,教师在阅读与使用时要深入解读,领会文本中蕴含的知识呈现之理。一、在编排主线中理清知识目标根据螺旋上升的原则编排教学内容,数学各知识间存在一定的联系,教学中不能“只见树木不见森林”。在编排主线中理清知识目标,不仅有利于确
In mathematics teaching materials, the presentation of mathematical knowledge is first and then advanced step by step. This embodies the concept of gradual development of knowledge from simple to complex, from easy to difficult, and also conforms to the cognitive law of children from intuitionistic to abstract and simple to complicated. Textbook is the main carrier of mathematics knowledge, teachers should read deeply when reading and using, and understand the reason of the knowledge contained in the text. First, sort out the knowledge target in the main line of arrangement According to the principle of spiraling, arrange the teaching content, there is a certain connection between the various knowledge of mathematics, and the teaching can not “see the trees without seeing the forest.” Sorting out the main knowledge of knowledge goals, not only conducive to the true
