长期以来,学生习惯了由教师把“已知”的东西传授给自己的接受性学习方式,数学课堂教学中普遍存在忽视知识的发生过程,忽视学生主体地位的现象,从而造成了学生学习兴趣不高,探索精神与创新意识的匮乏,极大妨碍了全体学生整体素质的提高.而“有效的数学活动不能单纯地依赖模仿与记忆,动手实践、自主探索、合作交流是学生学习数学的重要方法.”利用合作学习可以提高一定时间内学生学习、交往、表达的效率,达到优势互补,有利于培养学生的探究意识和合作精神,也
For a long time, students are accustomed to the teacher to “known ” something to their own way of receiving learning, mathematics classroom teaching generally ignore the occurrence of knowledge, ignoring the phenomenon of the dominant position of students, resulting in student learning Lack of interest, exploration spirit and lack of awareness of innovation, greatly hinder the improvement of the overall quality of all students. “Effective mathematics activities can not simply rely on imitation and memory, hands-on practice, independent exploration, cooperation and exchange students learn mathematics . ”The use of cooperative learning can improve the efficiency of students ’learning, communication and expression within a certain period of time, achieve the advantages of each other, and help develop students’ awareness of exploration and cooperation.
