Problem based learning is based on self-directed learning which is performed in small groups.
In PBL, the starting point for learning is a problem or query which the students wish to solve. After individual research, students then share their new information with group members, while applying the information to the problem. Once this process is over, students evaluate how effectively their group worked together, and discuss what changes can be made to improve the group dynamics for the next problem. In working in a group in this way, it is believed that students learn more, learn better, and learn interpersonal and team building skills that are needed for a successful career.
