积累 提炼 整合 发展——“面积和面积单位”的教学体会

Accumulation,Refinement,Conformity and Development

教师教面积和面积单位这样的概念时,如何帮助学生理解面积的意义和建立常用面积单位的准确表象?教师需为学生提供大量有序的材料,让学生积累感性经验,引导学生在对材料进行比较时提炼出本质要素,并正确把握新旧知识的连接点,完善学生的认知结构,把概念教学过程变成学生素质发展的过程。

The teacher teaches the area and the Square measure on how to help the student to understand the significance of the area and the establishment of accurate representation of square measure？ The teacher must provide the massive material for the students,let the student accumulate perceptual experience,guide the students to refine the essential factors through comparison of the materials,let the students have an accurate junction between the new and old knowledge,perfect the student＇s cognitive structure and finally turns the teaching process into quality development.
