浅谈情境认知理论视域下几何画板创设的初中数学情境

A Brief Discussion on the Middle School Mathematics Context Created by Geometric Drawing Board in the Contextual Cognitive Theory Perspective

摘要: 情境认知理论认为知识是在个体和情境的交互过程中产生的，情境是一切知识和技能获得的基础，其观点对数学学习情境的创设具有重要意义。本文旨在利用几何画板这一软件平台，输出直观性的数学信号，创设多种有效的数学情境，进而使数学知识形象化，激发初中学生自主探究的兴趣，加深初中学生对知识的理解，实现初中数学教学的高效化。

Abstract: Situational cognitive theory believes that knowledge is generated in the interaction between individuals and situations, and that situations are the basis of all knowledge and skills acquisition, and its perspective is of great significance for the creation of mathematical learning situations. This paper aims to use the software platform of geometric drawing board to output intuitive mathematical signals and create a variety of effective mathematical contexts, thus visualizing mathematical knowledge, stimulating junior high school students’ interest in independent inquiry, deepening junior high school students’ understanding of knowledge, and realizing the efficiency of junior high school mathematics teaching.
