[摘  要]   合作學習是新課改提倡的重要學習方式，已成為課堂教學的重要手段，是師生、生生之間合作學習、情感交流的重要途徑。本文結合實習期間在實習學校所聽研討課及指導老師的平時課，作為課例來源加以研究，通過觀察、分析數學課堂中進行的合作學習主要存在如下問題：1.合作學習流于形式2.合作學習中缺乏合理角色分配3.合作學習中忽視過程4.學生缺乏合作意識5.小組匯報形式化。針對以上問題提出了如下策略：1.教師應適時參與小組討論，了解合作情況2.小組內成員角色的分配應根據情況輪流3.教師應樹立正確的觀念 4.合作學習前應重視學生合作技能的訓練5.采用多樣化的小組匯報方式，調動學生積極性。

[Abstract]  The important learning promoted in the new curriculum is cooperative learning that has become an important mean of classroom teaching .The cooperative learning is also an important mean of emotional communication for teachers and students. In this paper, seminar Lessons and the instructor’s usual courses of practice school are lesson sources to be studied. Through observation, analysis of cooperative learning in the mathematics classroom, it concludes that cooperative learning has the following problems: 1. A mere formality; 2. Lack of reasonable rules; 3. Ignore the process; 4. Students are not good at cooperation; 5.a single form of group reporting and so on. Proposed the following strategies to solve the above problems: 1. The teachers should be timely to participate in panel discussions to master the situation of cooperation; 2. The roles within the group should be taken turns according to the circumstances; 3. Teachers should establish a correct concept; 4. Teachers should pay attention to students' cooperative skills training before cooperative learning; 5. Diverse group reporting, and engage students.
