Abstract

Purpose: To compare learning strategies used in Problem based learning (PBL) and lectures, and the relations between learning strategies and learning outcomes to determine how different learning strategies associated with PBL and lectures contribute to aspects of clinical competence. Design: The 52-item learning strategies questionnaire was given to preclinical medical students during lecture and PBL sessions in first and third year from 1994 to 1998. Response patterns were compared across the two contexts and factor structures investigated. Regression analyses examined relations between learning strategies and outcomes. Main Outcome Measures/Results: Comparison of responses on the 326 complete pairs of lecture and PBL questionnaires indicated differences at the 0.05 level on 44 of the 52 items. The mean differences were greater than 0.5 (on a 5 point scale) at the 0.001 level for 20 items. Of these, five strategies were used more often in PBL and 15 in lectures. Comparisons of learning strategy use across years showed significant changes with time in both instructional contexts. Principal component analysis revealed a stable factor structure with 4 factors distinctly associated with PBL and 4 factors with the lecture learning context. The remaining 6 factors were mixed and independent of context. Exploratory regression analysis revealed that learning outcomes in examinations were influenced by learning strategies. Multiple choice performance was positively predicted by learning associated with lecture class notes and negatively by group work, whereas the OSCE (objective structured clinical exam) performance was positively predicted by class participation in PBL, self-directed note making and lecture class notes. Conclusion: We have developed a learning strategies questionnaire that shows that students' learning strategies are influenced by instructional context, and patterns of learning strategy use change over time. There is tentative evidence that the students' learning strategies influence learning outcomes.
