Problem-based learning (PBL) is an instructional approach which enables learners to simultaneously develop problem-solving strategies, disciplinary knowledge, and research skills. Students become active problem solvers confronted with a hypothetical problem which mirrors real world problems.
PBL begins with the introduction of the said hypothetical problem on which all learning centres. Teachers assume the role of cognitive coaches rather than knowledge disseminators. Students assume the role of active problem-solvers, decision-makers, and meaning-makers rather than passive listeners.
