知识迁移力是数学学习的一个重要的能力,该能力的提升需要在夯实基础、构建知识网络,创建问题条件与结论之间的关联,注重对问题的分析、归纳、综合和反思的过程中逐渐形成并提升.本文依托余弦定理的讲解,从课堂教学的实例出发,阐述如何提高学生的数学知识迁移能力. Knowledge transfer ability is an important ability for mathematics learning. The improvement of this ability requires the consolidation of the foundation, the construction of a knowledge network, the creation of the relationship between problem conditions and conclusions, and the gradual emphasis on the process of analyzing, summarizing, synthesizing, and reflecting on problems. Form and promote. This article relies on the cosine theorem to explain, from the examples of classroom teaching, elaborates how to improve the students’ knowledge transfer ability.
