学习反思是学生学习过程重要一环。建构主义学习观认为:一切知识最终都必须通过主体的建构活动才能得以完成,学习不是被动的接受,不是单纯地复制与同化,它要求学生在活动中进行建构,要求学生对自己的活动过程不断地进行反省、概括和抽象。显然,学习中的反思如同生物体消化食物和吸收养分一样,是别人无法代替的。反思是建构主义的一个核心特征。关注学生学习过程的反思,可以促进学生自主学习能力的提高。为了提高数学学习效率,必须使学生有时间、有机会对自己思维活动进行反思,对自己是怎样发现 Learning reflection is an important part of the learning process of students. Constructivism learning view that: all knowledge must ultimately be completed through the construction of the main activities, learning is not passive acceptance, not simply copying and assimilation, which requires students to construct in the activities, requiring students to keep their own activities Reflect, summarize and abstract. Obviously, reflection in learning is like other organisms that can not be replaced by others, just like digesting food and absorbing nutrients. Reflection is a core feature of constructivism. Focusing on the reflection of students ’learning process can promote the improvement of students’ autonomous learning ability. In order to improve the efficiency of mathematics learning, students must have time, have the opportunity to reflect on their own thinking activities, how to find out for themselves
