PROBLEM BASED LEARNING (PBL)


Problem-based learning is student-centered teaching-learning strategy in which students collaboratively solve the problem and this reflects on their experience. In problem-based learning, the starting point is a problem, a query, or a puzzle that the learner wishes to solve (D.L. Bound, 1985).

It is a careful inspection of methods, which are permanently successful in formal education. In PBL, students depend for their efficiency upon the fact that they go back to the type of situation, which causes reflection out of ordinary life (John Dewey, 1916).

PBL is a process of acquiring and understanding of knowledge, skills and attitude in the context of an unfamiliar situation and applying that learning to the situation. There are four components of PBL:
  1. Non-lecture format and teacher acting as a facilitator.
  2. Presentation of real world situation or problem from ordinary life.
  3. Group work and group discussion.
  4. Student-directed solution of the selected p
  5. roblem.
