Given the limited application of adaptive training to military tactical training in a scenario-based context, there is little guidance from empirical research on which variables to adapt, how and when to adapt training feedback, and the types of training effectiveness benefits that may be realized. This effort leveraged and extended extant guidance to judiciously select and evaluate adaptive, metacognitive, real-time feedback approaches to improve tactical decision making (Jonassen & Tessmer, 1996). Feedback was incorporated into a tactical scenario, prompting students to think about allocating tactical resources based on capabilities and limitations and to manage scenario events. Findings indicate that there are increases in tactical knowledge about a scenario when Surface Warfare Officer (SWO) trainees receive metacognitive real-time adaptive feedback versus post scenario debrief on scenario events.
