Exercising
A meeting is followed by exercises. Tasks are carried out using the teamwork approach. Often the group work can be further sub-divided into smaller tasks for every group member - nearly always true for coding tasks. Even with this sub-division the group should stay together in the same room, although every team member may be working on their own. If a problem arises all group members immediately work together to find a solution. Group members help each other on demand. If the task is a coding task, pair programming is recommended but is not mandatory. If a new group member joins an existing group every question has to be answered patiently. Therefore the concept of small changing groups make tutees learn from each other.
