A Web-based approach to teaching students about diagnostic reasoning

Web-based curricula can decrease classroom time and provide self-paced, active learning experiences for medical students. In our family medicine clerkship, we implemented a Web-based module on applying diagnostic reasoning to determine the likelihood that a patient has Group A beta-hemolytic streptococcal pharyngitis based on the history, physical examination, and diagnostic tests. Students rated the module more favorably than other classroom sessions and homework assignments. Most students accurately calculated pretest and posttest probabilities in a write-up of an actual patient with a sore throat. This Web-based module was well received and effective.
