On the additional value of lectures in a problem-based curriculum.
OBJECTIVE
The purpose of this article is to report on a study conducted to investigate the additional value of lectures in problem-based learning. We hypothesized that lecture quality, as indicated by students, would have a positive influence on time students would spend on self-study, that they would increase intrinsic interest in subject matter and would have a positive influence on achievement. Lecture quality would, in this view, add to other factors that play a role in problem-based learning, such as prior knowledge of students, the quality of problems presented, the functioning of the tutor and small-group collaboration.


METHODS
The hypothesis on the influence of lecture quality on learning was assessed by means of testing a structural equating model, using data from 1500 students.


CONCLUSIONS
We concluded that lecture quality does not affect time spent on study, does not add to achievement and does not influence intrinsic interest in subject matter. Post-hoc analysis, however, demonstrated the quality of lectures was related to other components of problem-based learning, not part of the presented model, such as students' perceptions of lectures as organizer of their study efforts or lectures as a means of putting the problems into a broader perspective.
