KEY CONCEPTS
Problem-Based Learning (PBL) is a pedagogical approach and curriculum design methodology often used in higher education and K-12 settings[1][2].
The following are some of the defining characteristics of PBL:
Learning is driven by challenging, open-ended problems with no one “right” answer
Problems/cases are context specific
Students work as self-directed, active investigators and problem-solvers in small collaborative groups (typically of about five students)
A key problem is identified and a solution is agreed upon and implemented
Teachers adopt the role as facilitators of learning, guiding the learning process and promoting an environment of inquiry
Rather than having a teacher provide facts and then testing students ability to recall these facts via memorization, PBL attempts to get students to apply knowledge to new situations. Students are faced with contextualized, ill-structured problems and are asked to investigate and discover meaningful solutions.
