Problem Based Learning: An instructional model and its constructivist framework

this paper is to provide a clear link between the theoretical principles of constructivism and the practice of instructional design and the practice of teaching. We will begin with a basic characterization of constructivism identifying what we believe to be the central principles in learning and understanding. We will then identify and elaborate on eight instructional principles for the design of a constructivist learning environment. Finally, we will exam what we consider to be one of the best exemplars of a constructivist learning environment -- Problem Based Learning as described by Barrows (1985, 1986, 1992) at the Southern Illinois University Medical School and at the Problem Based Learning Institute for high school teachers .
