《数学课程标准》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。”合作学习在当前小学数学中已成为一种重要的教学组织形式,这不仅是当今课程改革的需要,也是时代发展的需要。小组合作学习为所有的学生提供了成功的机会。数学问题往往可以用不同的方法加以解决,通过小组合作的形式,每个学生都有机会提出自己的解题方法,同时又分享别人的解题方法,共同讨论不同的优缺点。这对于发展学生的解题思路,增强学生的自信心、培养学生的创造性思维十分有利。“合作交流”提供课堂平等交流的机会,培养与人交流协作的能 The standard of mathematics curriculum states: “Effective mathematics learning activities can not rely solely on imitation and memory, hands-on practice, independent exploration and cooperation and exchange and communication are important ways for students to learn mathematics.” Cooperative learning has become one of the current primary mathematics It is not only the need of the current curriculum reform, but also the need of the development of the times. Group collaborative learning provides a chance for all students to succeed. Mathematical problems can often be solved in different ways. Through group cooperation, each student has the opportunity to propose their own problem-solving methods and at the same time share the solution of others to discuss different strengths and weaknesses. This is very beneficial to the development of students’ problem-solving ideas, enhancing students’ self-confidence and cultivating students’ creative thinking. “Cooperation and Exchange ” Provide opportunities for equal exchange in the classroom and cultivate the ability to communicate and collaborate with others
