RESUMO
CONTEXT: Bedside clinical teaching is the backbone of clerkship education. Data-driven methods for supplementing bedside encounters with standardized content from vetted resources are needed. OBJECTIVE: To compare a flipped-classroom versus an interactive online-only instruction for improving knowledge, skills, self-directed learning (SDL) behaviors, and satisfaction in a medical school clerkship. METHODS: An IRB-approved prospective study employing a peer-reviewed clinical reasoning curriculum in neurology was conducted; 2nd-4th year medical students rotating through a required clerkship were enrolled. Students were randomized to flipped-classroom (i.e., flipped) or interactive asynchronous online instruction (i.e., online-only), which supplemented existing bedside teaching. Baseline and end-of-course knowledge, skill development, SDL behaviors, satisfaction, and long-term retention were assessed by peer-reviewed clinical reasoning exam, NBME scores, faculty/resident clinical evaluations, non-compulsory assignment completion, end-of-clerkship surveys, and objective structured clinical exam (OSCE). RESULTS: 104 students (49 flipped, 55 online-only) were enrolled. Age, gender, and training level did not differ by group (all p > 0.43); baseline knowledge was higher in the flipped group (p = 0.003). Knowledge-based exam scores did not differ by group even after adjusting for differences in baseline knowledge (2.3-points higher in flipped group, 95%CI -0.4-4.8, p = 0.07). Clinical skills were significantly higher in the flipped group, including examination skills (4.2 ± 0.5 vs. 3.9 ± 0.7, p = 0.03) and future housestaff potential (4.8 ± 0.3 vs 4.5 ± 0.6, p = 0.03). Students in the online-only group were more likely to engage in SDL (42 vs. 12%, p = 0.001) and reported more hours studying (6.1 vs. 3.8 hours, p = 0.03). Satisfaction (p = 0.51) and OSCE scores (p = 0.28) were not different by group. CONCLUSIONS: In this comparative study of two evidence-based curricular delivery approaches, we observed no difference in knowledge acquired. Greater clinical skills were observed with flipped instruction, while more SDL was observed with online-only instruction. Supplementing bedside teaching with blended instruction that balances live skill development with vetted online resources is optimal for clerkship education.

Education up to the latter part of the 20th century used strict methods of instruction delivery, relying mostly on tried theories in cognition and social learning. Approaches in constructivism and collaborative learning affirm the success of existing methods of delivering curriculum, yet they also validate the use of information technology as a vehicle to improve student learning.
