Increasing threats in the area of information security raise the necessity for companies to be prepared for a digital forensic investigation. However, even the best investments in technology and infrastructure will fail if employees are not adequately trained. In this paper we propose a workshop concept combining the peer instruction method and elements from the field of serious games. The goal of the combined methods is to enable the participants to investigate a use case in an interactive and playful way. Our concept guides the participants step by step into an increasingly independent way of performing a digital forensic investigation.
