It has been suggested that problem-based curricula can lead
to increased retention of knowledge, enhanced integration of
basic scientific concepts, development of self-directed learning
skills and increasing intrinsic interest in the subject matter
being learned (Dolmans and Schmidt, 1996). PBL students have
been found to be more likely to study for meaning than
conventional students (Newble and Clarke, 1986), though
Groves (Groves, 2005) suggests that this is unlikely to occur if
the assessment is not supportive or the work load is excessive.
