The rapid development of digital technology has expanded the prospects and promises for its application in physical education programs. Physical educators are becoming increasingly interested in technology but often remain inadequately equipped to effectively integrate these technological resources in their daily practice, and/or lack the practical knowledge about the potential of these digital resources. For example, various commercial digital applications (apps) for games-based teaching are available to support instruction and feedback, such as video analysis apps. But these promising technological innovations are sometimes applied incorrectly or may even overtake the teaching focus at the expense of the pedagogical and didactical aims. The purpose of this article is to describe the process of innovating, introducing and developing a digital tagging application for teaching tactical awareness in sport games. This case study illustrates how physical educators implemented a video analysis app to provide feedback and develop students' tactical awareness in games. It demonstrates how innovative digital resources can be implemented in physical education, while supporting the central tenets of games-based approaches to teaching games.
