建构主义的学习观认为,学习不是教师把知识简单地传递给学生,而是学生自己建构知识的过程。在学习过程中,学生不是被动地接收信息,而是以原有的知识经验为基础,主动建构知识的意义。《义务教育数学课程标准》指出:要重视从学生的生活实践经验和已有的知识中学习数学和理解数学。传统的数学教学把眼光只盯在课本上,远离了生活的源泉,使教学成了无源之水、无本之木。学生与教师迷失了方向,模糊了学习与教学的目标,失去了学 The constructivist view of learning holds that learning is not a process in which a teacher simply passes on knowledge to a student but a student’s own knowledge-building. In the process of learning, students do not passively receive information, but rather take the initiative to construct the meaning of knowledge based on the original knowledge and experience. “Compulsory education mathematics curriculum standards” pointed out: Emphasis should be placed on learning mathematics and comprehension of mathematics from students’ practical experience and existing knowledge. The traditional teaching of mathematics focuses on the textbook only, far away from the source of life, making teaching a passive water without a foundation. Students and teachers lose their way, obscuring the goals of learning and teaching, losing their studies
