摘要
为了揭示问题的本质和规律,人们可以从不同侧面对数学题目进行研究。这就用到解题变式的三种形式:一题多解、一题多变和多题归一。作为一种现代教育技术手段,"几何画板"具有追踪轨迹、实时计算等功能,因此,为了降低认知负荷,它可以用以实施解题变式。同时,在数学解题变式中应用"几何画板",能够增加学生的内在驱动力和学习主动性,能够培养学生的学习兴趣和创新能力。
In order to reveal the essence and the rule of math problems, we can make research from their different flanks. In this process, three forms of math problem-solving variants can be used： many solutions to one problem, one problem with different forms; one solution to many problems. As a modem technical measure, geometrical drawing board has such functions as tracing orbit and real-time calculation. It can stimulate students to work hard and spontaneously, and foster their learning interest and innovation ability to employ geometrical drawing board in math problem-solving variants
