Contextualized problem Small group work Students as actors analyze problem and reactivate previous acquisitions (90 min) Teacher as a facilitator Motivation stimulated by feedback (peers, tutor) Autonomy reinforced by individual search of information PBL fundamentals PBL inspired lecture • Contextualized short scenario to begin with • Small group work: 6-10 students convene around the tables in the lecture room • They interact in clarifying new terms, identifying and discussing key messages (20 min) • Teacher collects questions, opinions and stimulate student answers (20 min) • Lecture (interactive) with reference to student productions where relevant (90 min)
A mother seek advice about her 13.5 yr old twin son possibly repeating grade due to recent collapse of schoolnotes while her twin daughter is brilliant and successful. The twin sister started pubic hair at 7, breast budding at 9 and she grew very fast at 10. She got her first periods at 11 and now, she looks like an adult woman with a height of 167 cm. Mother was concerned by her precocity because she heard that growth could stop prematurely. The twin brother is 142 cm tall and feels behind. He went to a doctor who explained that his puberty just started based on an increase in testicular volume. He predicted peak height velocity to occur between 15 and 16. This was consistent with a delayed bone age (11 yrs). He wants hormonal therapy to speed up development but mother is reluctant. The scenario

Students: they are motivated for this particular course since they elected to follow it even before the PBL inspired format was used Students: they are enthusiastic when hearing about patients after so many years of mainly theoretical teaching Students: they have few or no experience of group work and self-expression in a large group Teacher: as a PBL- or lecture- motivated person, motivation may be the key instead of the PBL or lecture format The biases: factors unrelated to PBL
In a traditional lecture setting, it is possible to introduce some components of PBL through an initial student activity in small groups around a short scenario and subsequent sharing of their reflexion with the whole class The evaluation modalities should be consistent with the learning conditions Overall, such an initiative is well received by the students though it is hard to separate the contribution of specific PBL components from others (novelty, practicality, motivation) A long-term impact could be expected based on student comments: « was in; made links; had to think about; had to take a position; discovered other perspectives; too much medicine but so great to touch professional realities,… » Conclusion
