Comparing teaching with tactile guidance with video modeling with self-evaluative video feedback to train medical skills

Modern medical training consists largely of lecture-based instruction and in vivo or video modeling of specific skills. Other instructional methods, such as teaching with acoustical guidance (TAGteach), have rarely been evaluated. In this study, we compared teaching with tactile guidance, or tactile TAGteach in which a vibratory stimulus is delivered to indicate a correct response, with video modeling and self-evaluative video feedback to teach four participants two medical skills: simple interrupted suture and endotracheal intubation. The results showed that both instructional methods improved performance. However, three participants met the mastery criterion in the tactile TAGteach condition first, although this instructional method required more time to train the skills. We discuss the implications of these findings for training skills to medical practitioners.
