The introduction in 2006 of problem-based learning (PBL) into engineering courses in schools of Electrical and, Architectural, Civil and Mechanical Engineering (ACME) constituted a paradigm shift in engineering education at Victoria University (VU). It was hoped that such a pedagogical approach would attract a higher calibre of students to engineering courses at VU and reduce the high attrition rates. In the short time since it was introduced, it is difficult to gauge whether the implementation of PBL teaching has been an unqualified success. Anecdotal evidence, at this stage, suggests mixed educational outcomes. This paper examines theoretical frameworks of PBL in professional education and, specifically, the accepted wisdom that PBL education is convergent with professional engineering discourses. The author is supportive of a pedagogy which embodies constructivism but argues that this is not a property of a definitive PBL model and that it does not necessarily need the vehicle of a PBL. It needs to be kept in mind that a single PBL model as a definitive framework for educational delivery has many inherent flaws and it should be introduced in a context and be treated as work in progress.
