数学史“重构式”融入小学数学教学的研究——以“认识厘米”为例

The History of Mathematics Integrating intothe Elementary Mathematics Teaching by Restructuring:Taking Centimeter for Example

"重构式"被认为数学史融入数学教学最难的一种方式。以"认识厘米"为例,具体地可以分成以下几个步骤:第一,梳理所教主题的历史;第二,理解所教主题历史进化的主要步骤;第三,重构关键思想或步骤;第四,问题驱动设计教学。在实施过程中应以历史发生原理为主要依据,以知识的发生、发展历史为基础,而理性重构数学史是关键。

Restructuring is regarded as the most difficult way in the integration of mathematics history and mathematics teaching. Taking Centimeter for example, it includes the following steps. First, searching for the history of the topic. Second, addressing the main step of the history. Third, restructuring the key thinking or steps. Finally, designing the teaching with questions promoting. When implementing, we should take historical-genetic principle as the base, the occurrence and development of the mathematics knowledge as the foundation and restructure the mathematics history rationally as the core.
