In the workplace, employers often look at potential employees and evaluate their interactive skills. These are skills that allow you to interact well with others in the workplace, and help you be a productive member of a team. Group work or collaborative learning is a great way to help students develop these in demand skills.
Humans usually gravitate to working in groups. It is part of our nature. We often associate with groups because of the social aspects; however, in a higher education environment, the purpose of the group is to identify and execute learning activities.
It is important when attempting to design group work courses and activities to make sure you know what you want the group structure to look like. Most groups are successful when they have a limited number of members. Limiting members to between 3 and 6 members is ideal. Too many members produce group situations where some students are not very active in the group, and less members can cause the students to feel overwhelmed with the workload of the groups.
