Summary
Problem-based learning (PBL) in epidemiology education is academically equivalent to traditional methods, offering a richer learning experience. PBL enhances student enthusiasm and grasp of principles without increasing overall study time.
Area of Science:
- Medical Education
- Epidemiology
- Pedagogy
Background:
- Traditional teaching methods are standard in medical epidemiology courses.
- Problem-based learning (PBL) offers an alternative pedagogical approach.
- Evaluating the comparative effectiveness of PBL versus traditional methods is crucial for curriculum development.
Purpose of the Study:
- To compare the academic outcomes and student experiences of traditional versus PBL teaching methods in an undergraduate epidemiology course.
- To assess student performance in epidemiology through a controlled trial.
Main Methods:
- A randomized controlled trial was conducted with second-year medical students (n=80).
- Students were assigned to either a PBL or traditional epidemiology course stream.
- Academic performance was evaluated using identical quizzes and exams; student feedback and interviews were also collected.
Main Results:
- No significant differences in quiz or exam scores were observed between PBL and traditional groups.
- PBL students reported a stronger understanding of epidemiologic principles and greater enthusiasm for the subject.
- PBL students perceived epidemiology as more professionally relevant and enjoyed group work more than traditional students.
Conclusions:
- Problem-based learning (PBL) offers an academically equivalent, yet more engaging and enriching, learning experience in epidemiology.
- Further research is needed to address potential challenges of PBL for non-native English speakers in medical education.
