数学课堂是一个小型的数学共同体,它应成为共同成员之间交流数学思想的场所。因此,教师在教学中应努力给学生搭建交流的平台,通过班级、小组或者朋友之间的数学交流,逐渐学会清晰、准确而有逻辑地表达自己的思想,善于倾听别人的理解,内化别人的思想,以达到对知识的主动构建,提高数学思维水平。一、营造和谐氛围——实现有效交流的基本点建构主义者认为:“为了促进学生的知识结构,教师要创设平 The mathematics classroom is a small mathematical community that should be the place where the common members exchange mathematical ideas. Therefore, in teaching, teachers should strive to build a platform for students to communicate and gradually learn to express their thoughts clearly, accurately and logically through mathematical exchanges among classes, groups or friends, be good at listening to other people’s understanding and internalizing others In order to achieve the active construction of knowledge and improve the level of mathematical thinking. First, to create a harmonious atmosphere - the basic point of effective communication Constructivists think: ”In order to promote the student’s knowledge structure, teachers should create a flat
