《数学课程标准》指出:“动手实践,自主探索与合作交流是学生学习数学的重要方式。”在教学过程中,无论是合作学习,还是展示探究的过程与结果,都需要用一定的数学语言准确地予以表达,这就是交流。交流可以帮助学生相互学习取长补短,彼此分享,提高学习效率。那么怎样在数学课堂教学中 “Mathematics Curriculum Standard” states: “Hands-on practice, independent exploration and cooperation and exchange are important ways for students to learn mathematics.” In the process of teaching, whether it is cooperative learning or displaying the process and result of inquiry, Mathematical language to be accurately expressed, this is the exchange. Communication can help students learn from each other, share with each other and improve learning efficiency. So how in mathematics classroom teaching
