建构主义认为,学习不是被动的传授知识,而是学生主动地建构知识,教师只是学生建构知识的帮助者、引导者和促进者。概念是所有教学环节的重点,它反映了一类事物的固有属性,概念教学的效果直接影响思维深刻性的发展。几何画板的软件环境在解析几何教学和学习中为建构主义应用于数学课堂提供了一个逼真的学习情境,加深学生对概念本质属性的理解。本文以椭圆的概念教学为例,研究几何画板对思维深刻性的影响。
Constructivism believes that learning is not passively imparted knowledge, but students take the initiative to construct knowledge, teachers are only students to help build knowledge, guide and facilitator. Concept is the focus of all teaching, it reflects the inherent properties of a class of things, the direct impact of the concept of teaching the development of profound thinking. Geometry Sketchpad’s software environment provides a realistic learning context for constructivism in analytic geometry teaching and learning, deepening students’ understanding of the essential nature of concepts. In this paper, the concept of elliptical teaching as an example, the study of geometrical drawing board on the profound impact of thinking.
