Two heads are better than one. It means that two people working together have a better chance of solving a problem than one person alone. But not everyone likes working in a group.

    There can be a number of reasons why people dislike group work. Some may feel nervous or uneasy in group situations. Others might have had a bad experience with individuals who did not work well as a team. Another comment is that teachers or instructors fail to provide roles for group members. This may create a situation where everyone or no one wants to lead. Whatever the issue, the result is the same: the group does not realize its goal.

    Cooperative (合作的) learning is an educational method that can help to solve this problem. There are many methods of cooperative learning. Today we will talk about one: giving each person in a small group a specific duty to reach a shared goal. For example, if learners are divided into groups of four people each, their roles might be: leader, writer, checker and speaker. This structure helps ensure that everyone takes part equally in group work and allows each member to play a meaningful part in completing the shared goal.

    Before dividing learners into groups, it is a good idea for the teacher or club's instructor to first have knowledge about the language skill levels of participants. The goal is to make each group a mixture of higher- and lower-level language learners. Putting too many people with similar skill levels together could make the work too difficult or easy. Role cards can be a helpful tool in this method of cooperative learning. Their purpose is to remind learners of each person's role.

    Before the cooperative activity, the role of the teacher or activity instructor is to explain two things to the group: the main job for the activity and how the cooperative roles work. The person in charge may appoint these roles or let the English learners choose them. Then, during the activity, the instructor's job is to watch the groups and provide more guidance when needed. After the activity, the instructor may wish to provide feedback to groups on their work and their use of cooperation.

    With this cooperative learning method, you can say that four heads are better than just one.
