Deliberate Practice vs Lecture Review: CPR Skill Acquisition

This simulator compares two ways of training a hands-on clinical skill — correct chest-compression technique — using a 3D CPR training mannequin. In "Lecture Review" mode, replaying the same instructional content over and over builds conceptual familiarity but leaves the measured competency score flat and low, because no physical practice occurs. In "Simulation Practice" mode, each repetition is a hands-on attempt scored against target compression depth (5–6 cm) and rate (100–120/min), and the live feedback after every attempt drives steadily climbing competency toward a proficiency threshold. Switch modes, run repeated repetitions, and watch the competency-vs-repetitions chart trace both learning trajectories side by side.
