| Cooperative group is an important organizational foundation for cooperative learning, which has a direct impact on the effectiveness of cooperative learning. The cooperative learning often encounter "the willingness of cooperation is not strong 、lacking of cooperative ability、conflict frequently, diffusing of group responsibility "and so on. These problems are common problems in the process of the construction of organization, which is clearly related to the construction of team.We found that there are three different types of cooperative learning group construction through the field survey.That is extensive group construction 、utility-type team construction and the connotative group construction. These three different types have different methods which revolve around eight points : team construction, selecting and training group leader, constructing team culture, to determine the role and responsibility, choosing the field of group cooperation, training team cooperation skills, establishing system of evaluation , improving teachers’guidance. This paper sums up the concrete practices of three different types of group construction and presents the feedback of students and teachers to the construction of three types of groups by questionnaire and in-depth interviews.The survey shows:① The extensive group construction failed to highlight the"cooperation" theme. most of the students failed to comprehend the significance and value of cooperation, the willing of cooperation is not high, the cooperation ability is poor, which can not guarantee the effectiveness of cooperative teaching.② The utility-type team construction has basically completed the expected tasks. Most of students have a certain sense of teamwork, the group is in line with the characteristics of the team, and the team operate stable, which can reflect the advantages of group cooperative learning. However, its value orientation is too utilitarian, which only focused on the subject of learning and avoiding other fields except for learning. This limits further development of the group. In addition, the majority of practices of team building are based on intuition and experience summary, which lack theoretical character.③ The connotation of group construction lay a foundation for the cooperation between students.Both teachers and students can obviously feel better in interpersonal atmosphere, but in the subsequent efficient operation level remains to be further improved.Based on the investigation we summarize the factors that determine the di recti on of group construction:① Whether builders can accurately understand the nature of team construction or not;②Whether the school managements in the pr ocess of carrying out curriculum reform are fully prepared、confident and reaso nable or not;③Whether choosing teachers are appropriate or not;Then we respe ctively propose optimization strategies from the school and teachers’ view for e ach type of team construction. Suggestions for school mainly include: ①Persist t he curriculum reform and treat group construction as a breakthrough in coopera tive learning;②Respect teachers pragmatically and pay attention to encourage te achers;③ Seek guidance to improve the level of teachers’ team construction;④Adjust general ideas of team construction to avoid the tendency of pragmatism;Suggestions for teachers mainly include: ①To be diligent in action among teach ers’ cooperation and constantly improve the level of team construction ;②Con struct team first work and then strive for efficient operation;③Expand the sco pe of cooperation group;④Transform and apply relevant achievements in team building into the construction of cooperative learning group. |
