谈数学学习中前概念的转变策略

On the Transformative Strategies of Pre-concept in Mathematics Learning

学生在学习科学概念之前,已经形成了对各种自然现象的看法,同时也养成了他们独特的思维方式。这种在接受正规的科学教育之前所形成的概念一般称之为前科学概念(或前概念)。教育过程必须立足于学生头脑中的前概念,把前概念作为产生和孕育科学概念的“必然生长点”。

Before the study of scientific concepts, students have already formed their views on all kinds of natural phenomena. At the same time, they form their specific ways of thinking. This kind of concept formed before students' accepting of formal and scientific education is generally called pre-scien-tific concept or pre-concept. The course of education must be based on the pre-concepts in students' mind, and regards them as the essential growing point of engendering and gestating scientific concepts.
