所谓“再创造”是相对原始创造而言,它不是简单、机械地去重复再现历史,而是指在数学教学过程中,重新发现和创造,建立合理的数学认知结构,形成数学能力。“再创造”包括两个层面:一是教师的教学“再创造”,即教师对教学内容重新加工创造,充分展示获取数学知识的思维过程,创造性地设计教学 The so-called “re-creation” is relative to the original creation, it is not a simple, mechanical reproduction of history, but refers to the process of mathematics teaching, rediscovery and creation, the establishment of a reasonable mathematical cognitive structure, the formation of mathematical ability. “Re-creation” includes two levels: First, teacher’s teaching “re-creation” means that teachers re-process and create teaching content, fully demonstrate the process of acquiring mathematical knowledge and creatively design teaching.
