The primary objective of this study was to assess user reactions and perceptions of usability regarding the Combat Medic Card Game (CMCG). The CMCG was designed to serve as a supplementary study tool for individuals completing Combat Medic training in order to support and reinforce learning of emergency medical care procedures (e.g., hemorrhage management). In addition to collecting reaction and usability data, an exploratory study of user learning compared learning outcomes achieved using two different modes of card use: game play versus flash cards. Results suggested that users in the flashcard group were more likely to report perceived learning compared to users in the game play condition. However, declara-tive knowledge scores were not significantly different between conditions.
