荷兰数学家弗赖塔教授指出:“反思是数学思维活动的核心和动力。”可见,反思对于学生的数学学习和思维发展是何等的重要。《数学课程标准》也多次强调,数学教育必须重视学生反思意识和能力的培养。反思,其实是学生强化自我意识、进行自我监控和实现自我发展的内在需要和必然过程,是对学生数学学习活动过程的再思考、再认识、再定位和再决策,对于学生的自主学习显然具有特殊的意义,对于学生的终身发展也必然产生深远的影响。反思,不仅是一种思维形式和过程,更是一种具有创造性和发展性的实践活动, Dutch mathematician Professor Freita pointed out: “Reflection is the core and motivation of mathematical thinking activities.” It can be seen how important reflection is for students’ mathematical learning and thinking development. “Mathematics Curriculum Standard” also stressed many times, mathematics education must pay attention to students’ reflective consciousness and ability training. Introspection is actually the intrinsic and inevitable process of students’ self-awareness, self-monitoring and self-development. It is the re-thinking, re-understanding, re-orientation and re-decision making of student’s mathematics learning activities. Special meaning, for the life-long development of students will inevitably have a profound impact. Reflection is not only a form of thinking and process, but also a creative and developmental practice,
