经验的提升,是感性体验向理性思维迈进的必然需求。如果仅仅停留在经验的获得和积累上,学生的数学思维、数学能力就难以得到发展,数学学习活动只能游离于整个教学进程之外。在教学中,我们应当让活动经验所得从感性向理性跨越,进一步发掘数学活动的内在价值。一、延伸——从经验到方法经验是感性的,而且通常都是杂乱无序的。教师需要引导学生对活动中所得的经验进行梳理,鼓励学生将经验延伸 The improvement of experience is the inevitable demand of sensual experience toward rational thinking. If you only stay in the experience of gain and accumulation, students’ mathematical thinking, maths ability to develop hard, math learning activities can only be separated from the entire teaching process. In teaching, we should make the experience of activities from the perceptual to rational leap forward to further explore the intrinsic value of mathematical activities. First, the extension - From experience to methodological experience is perceptual, and usually are chaotic. Teachers need to guide students in sorting out the lessons learned from their activities and encourage them to extend their experience
