数学推理是学生获取知识的重要思维方式,也是学生掌握数学知识的重要探究方式。在数学推理中,学生可以亲历知识的来龙去脉,建立知识体系、归纳数学概念、获得数学规律。具备推理能力的学生思维会更灵活,考虑问题也会更加缜密,教师要直面课堂教学中的数学推理,演绎精彩数学课堂。本文从观察发现,在规律寻找中运用推理;联系实践,在分析比较中运用推理;一题多解,在多元解答中运用推理三个方面阐述。
Mathematical reasoning is an important way of thinking for students to acquire knowledge. It is also an important way for students to master mathematical knowledge. In mathematical reasoning, students can experience the ins and outs of knowledge, establish a knowledge system, summarize the concept of mathematics, access to mathematical rules. Students with reasoning ability will be more flexible in thinking, and the problem will be more meticulous. Teachers should face the mathematical reasoning in class teaching and interpret the wonderful math class. This article from the observation found that the use of reasoning in the law to find; contact practice, the use of reasoning in the analysis of the comparison; a solution of multiple solutions, the use of multiple solutions in the interpretation of the three aspects.
