Comparing video-based versions of Halsted's 'see one, do one' and Peyton's '4-step approach' for teaching surgical skills: a randomized controlled trial.

The modified video-based version of Peyton's '4-step Approach' is the preferred method for teaching especially complex motor skills in a large curricular scale. Furthermore, an effective way to utilize Peyton's method in a group setting could be demonstrated. Further studies have to investigate the long-term learning retention of this method in a formative setting.
