Endoscopy Education Grounded in the Science of Expertise and Simulation-Based Mastery Learning

This essay surveys endoscopy education from its historical roots to today's uneven outcomes, introduces the science of expertise-deconstructing expert skills, deliberate practice, and mastery learning-and explains how these principles reshape medical education. It then examines simulation-based mastery learning (SBML) as a platform to achieve mastery goals in endoscopy, emphasizing its role in clinical simulation, its potential to advance learning outcomes, and presenting representative examples of SBML in endoscopy. The piece identifies 4 sequelae of SBML programs and closes with a coda, urging broader adoption based on persuasive outcomes research and educating readers about a new approach in education.
