随着课程改革的不断推进,广大小学数学教师已经充分认识到,在数学课堂上充分调动学生数学学习的积极性,引导他们对数学知识进行自主探究是十分重要的。在“以学为中心”的小学数学课堂转型过程中,如何发挥小学生在数学学习过程中的主体地位成了当前数学教育界的一个热门话题。很多教育工作者在课堂教学中进行了有益的尝试与探索,总结了丰富的教学经验。课堂学习仅仅是小学生数学学习的一个阶段,并不是全部,课前预习与课 With the continuous advancement of the curriculum reform, most primary school mathematics teachers have fully realized that it is very important to fully mobilize the enthusiasm of students in maths learning in mathematics classrooms and to guide them to explore maths independently. In the transition process of elementary school mathematics classroom with “learning as the center”, how to bring primary school pupils into play in the process of mathematics learning has become a hot topic in mathematics education. Many educators in the classroom teaching conducted a useful attempt and exploration, summed up the rich teaching experience. Classroom learning is only a stage of primary school mathematics learning, not all, pre-class preview and class
