《数学课程标准》(实验稿)指出:“学生是数学学习的主人。”从本质上来说,学生学习数学的过程是一个自主构建对数学知识理解的过程。他们带着自己原有的知识背景、生活经验和理解走进学习活动,并通过自己的主动活动(包括独立思考、与他人交流和反思),去构建对数学的理解。因此,在数学教学中必须突出学生的主体地位,已成为大家的共识。那么,在数学教学中怎样突出学生的主体性学习,引导 The Mathematics Curriculum Standard states: “Students are the masters of mathematics learning.” Essentially, students’ learning of mathematics is a process of building their own understanding of mathematical knowledge. They enter learning activities with their own background, life experience and understanding, and build their understanding of mathematics through their own initiative (including thinking independently, communicating and reflecting with others). Therefore, in mathematics teaching must highlight the dominant position of students, has become the consensus of all. So, how to highlight the student’s subjective learning and guidance in mathematics teaching
