指向学生发展核心素养的数学概念教学——以“面积”概念教学为例

Mathematics Concept Teaching Oriented to Students' Development Core Accomplishments

概念的建立,不是概念术语的机械识记过程,也不是单纯的直观形象的简单累积过程,而是基于概念本质内涵的意义建构过程。以小学数学中"面积"概念教学为例,通过创设情境、激发需求、举一反三,从面有多大,到面积是多少,让学生经历从模糊到逐渐明晰的过程,内化面积概念本质。

Concept establishment is not the process of mechanically memorizing the concepts and terms, not the process of simply accumulating the visual image, but the process of meaning construction on the basis of the essential connotations of concepts. Taking the teaching of “area” concept in primary school mathematics for example, teachers create situations, spark students’ needs and infer other things from one fact to help students go through the process from vagueness to clarifi cation, so that they can internalize the essence of the concept of area.
