“在今天的知识经济时代,仅仅记忆事实性知识和程序性知识远远不够,重要的是能对知识形成深刻的概念性理解,并能基于这些理解生成新的观点、新的理论、新的产品和新的知识。”然而,当下的数学教学却明显存在着一些问题:一方面,我们的教学在主动地“追求”着学生,而学生被动地接受“追求”;一方面我们的学生在我们的训练下能够灵活运用数学知识、公式、定理来解答书面的问题,但在面对现实问题时却无从下手。或许正是基于这样的尴尬,《义 In today’s era of knowledge economy, mere memory of factual and procedural knowledge is far from sufficient. It is important that a profound conceptual understanding of knowledge be developed and that new ideas, new theories and new ideas be generated based on these understandings However, there are some obvious problems in current mathematics teaching: on the one hand, our teaching actively “pursues” students while students passively accept “pursuing ”; on the other hand, On the one hand, our students can use our knowledge of mathematics, formulas, and theorems to answer written questions flexibly under our training. However, they can not start to deal with practical problems. Perhaps it is based on this embarrassment, "justice
