《数学课程标准》明确指出:“有效的数学学习活动不能单纯地依赖模仿与记忆,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。”运用小组合作学习的方式来实现学习方式的多样化,建立自主、合作、探索、发现、研究等学习机制以提高教学质量,确实收到了良好的教学效果。但是,在平时的教学实践活动中,我深深地体会到许多教师不乏改革的热情,却往往缺乏一些冷静与理智的思考, “Mathematics Curriculum Standard” clearly states: “Effective mathematics learning activities can not rely solely on imitation and memory, hands-on practice, independent exploration and cooperation and exchange of students is an important way for students to learn mathematics.” The use of group cooperative learning to achieve learning The diversification of modes, the establishment of learning mechanisms such as autonomy, cooperation, exploration, discovery and research so as to improve the quality of teaching, and indeed received good teaching results. However, during the usual teaching and practice activities, I deeply understand that many teachers lack the enthusiasm for reform but often lack some calm and rational thinking.
