著名荷兰数学教育家费赖登塔尔强调:“反思是数学思维活动的核心和动力.”解题后的反思是学生在完成数学认知活动后,对自身的认知活动过程,以及活动过程中所涉及的有关事物的学习特征的分析、评价和自我调节的过程.即对解题活动的反思,对解题活动的深层次的再思考,是对数学解题学习的回顾或重复,更是深入探究数学解题活动中所涉及的知识、方法、思路、策略等,它是数学学习活动的重要环节,也是数学学习的主要方式 Feilidehal, a famous Dutch mathematician, emphasizes: “Reflexivity is the core and motivation of mathematical thinking activities.” Reflection after solving problems is the process of students’ cognitive activities after completing their mathematical cognitive activities, and The process of analysis, evaluation and self-regulation of the learning characteristics of the related things involved in the process of activity: the reflection on the problem-solving activities and the re-thinking on the problem-solving activities are the review or repetition of the learning problems in mathematics It is also an important part of mathematics learning activities and also the main way of learning mathematics, which is to further explore the knowledge, methods, ideas and strategies involved in the activities of solving mathematics problems.
