Cooperative Learning ?

Cooperative Learning is one of the best researched of all teaching strategies.Learning can be structured competitively, so that students work against each other; individually, so that students work alone; or cooperatively, so that students work together to accomplish shared learning goals. David W. and Roger R. Johnson, professors, and co-directors of the Cooperative Learning Center at the University of Minnesota, recommend that, while all three structures should be used, cooperation should play the dominant role in any classroom.
Cooperative learning is a successful teaching strategy in which small teams, each with students of different levels of ability, use a variety of learning activities to improve their understanding of a subject. Each member of a team is responsible not only for learning what is taught but also for helping teammates learn, thus creating an atmosphere of achievement. Students work through the assignment until all group members successfully understand and complete it.
Collaborative learning is a method of teaching and learning in which students team together to explore a significant question or create a meaningful project. A group of students discussing a lecture or students from different schools working together over the Internet on a shared assignment are both examples of collaborative learning.


Why use Cooperative Learning?

Research has shown that cooperative learning techniques:
* promote student learning and academic achievement
* increase student retention
* enhance student satisfaction with their learning experience
* help students develop skills in oral communication
* develop students' social skills
* promote student self-esteem
* help to promote positive race relations

In order for cooperative activities to be successful, teachers need to give attention to the following key elements:
A. Group Size/Composition -- Johnson and Johnson report the highest levels of success occur when groups are kept small. In fact, they favor groups of two (dyads) for many cooperative tasks, with the number of group members increasing in proportion to the complexity of the task. Teachers introducing cooperative learning for the first time might let students select their own groups. But once comfort is established, the greatest potential for benefit occurs in heterogeneous groupings, with the teacher assuring a balanced mix of ethnic groups, females/males, handicapped with non-handicapped students, and students of low-to-high ability and productivity.
B. Group Functions -- Students may work in groups on any of the assignments they would ordinarily do alone. They may meet to collaborate on solving a problem, to discuss an issue without direct leading by the teacher, to brainstorm for new ideas or summarize what they have learned about ideas previously presented, to formulate concepts out of information and facts they have been given. Particularly valuable is the potential of a group to share the parts of a complex project or jointly produce an assigned product. Goals for the group might range from practice in group communication processes to preparation for a presentation to the whole class group.
C. Group Norms -- Teachers need to proceed slowly and with patience to introduce students to cooperative learning. It is not enough to rearrange the seating. A "culture" of group work needs to be developed that includes expectations regarding noise level, an atmosphere of trust, absence of "put-downs," equal participation, and willingness to help one another. The use of group grades is controversial, but Johnson and Johnson report good results from encouraging "we sink or swim together" mindsets. It is important that students learn to coach and teach each other. Brighter students' learning is enhanced by their efforts to teach the others; less-capable students benefit from increased one-to-one attention.
D. Group Skills -- Students need to be taught procedures and given practice opportunities for rearranging the classroom space, moving quietly into groups, responding to teachers' signals for attention, etc. So, too, it is important for them to receive explicit instruction and regular practice in the interpersonal skills that this method, as well as life in a democratic society, requires. These include:
1. Teamwork
2. Support, and acceptance of differences
3. Active/reflective listening
4. Positive feedback
5. Reaching consensus
6. Coaching and tutoring others
E. Group Goals and Roles -- Clear instructions, goals, and time lines for group activities are essential to successful cooperative learning. It is also important that each member have a specific function within the group: recorder, reporter, monitor, observer, facilitator.
