Problem based learning
Problem based learning (PBL) has a significant history in medical schools. Recently it made reappearance as a constructivist method (Driscoll, p.405). PBL shares the collaborative method with Goal Based Scenarios. The students tend to work in groups and the primary learning goal is to solve a real problem. The learners are encouraged to use any available resources to develop a process to solve the problem.
PBL follows a systemic approach such as providing the students with a problem solving process that students utilized to identify the nature of the problem, identify the tasks and who is conducting them. Conduct a research to provide various solutions, arrive to a solution, evaluate the feasibility of their success or failure, and finally conduct a reflection on the efforts and the nature of what they have learned.
“PBL comes from a few medical schools, notably McMaster (Barrows and Tamblyn, 1980), where, more than 25 years ago, they questioned how well traditional preclinical science courses trained physicians to be problem-solvers and life-long learners.” The common method of teaching science is with lecture to large halls that usually contain 100 to 200 students. PBL allowed the medical school to focus on the actually practice of medicine that required integration of knowledge, decision making, working with others, and communicating with patients.
Various medical schools now include problem-based. “The effectiveness of the problem-based learning approach in the medical school environment has been debated, evaluated, and given qualified endorsement based on a limited number of studies (Albanese and Mitchell, 1993; Berkson, 1993; Vernon and Blake, 1993; Blake et al., 1995).”
The following website (http://www.udel.edu/pbl/dancase3.html) contains a fictional case study for an Anthropology professor who decided to conduct his class using PBL. I found the case study to be a revelation and a tribute to the difficulties of using a new pedagogue that the current students are not used to. Some of the negative comments reflected the lack of the student’s willingness to adapt new learning techniques. For instance, this comment was provided to the fictional professor by a student “student who complained that Prof. Sherman expected students to learn on their own and to spend too much time in the library tracking down obscure facts.”
PBL may require additional steps and may cause short-term headaches; however, it is a well-established process. The ultimate goal is to turn grades oriented learners into life long learners.
