Effectiveness of scaffolded case-based learning in anesthesiology residency training: a randomized controlled trial

Abstract Background: Medical residents often struggle with complex clinical scenarios that require sophisticated decision-making skills. While case-based discussion (CBD) is widely used in medical education, its effectiveness can be limited by insufficient guidance and structured support. Scaffolding teaching, which provides graduated assistance aligned with learners’ development, may address these limitations. However, evidence from randomized controlled trials evaluating the integration of scaffolding with CBD in residency training remains limited. This study aims to compare an integrated scaffolded case-based learning approach with
