Serious Games are an important part of technology aided learning. Since the learning outcome of intrinsically motivated learners is generally higher, a learning system should support the learner in achieving this state. Serious Games utilize the natural intrinsic motivation of playing a game by incorporating learning objectives. Concepts such as Digital Game Based Learning (DGBL) and Immersive Didactics achieve this by creating a learning environment that feels like an entertainment game by aligning learning and gaming goals. This puts players in a state of peaked intrinsic motivation which allows them to achieve increased levels of learning success -even while enjoying the game itself. Learning content for Serious Games is usually taken from existing courses or other materials. This work in progress explores the implementation of the interoperability standard LTI for integration purposes of third-party learning content into a Serious Game context.
