Every learning software is based on a learning theory. However, this is often not openly stated: the developers of the software are usually unaware of it, nor can it be inferred by educators from the use of the software. The book "Learning with Software" addresses this gap, which has often proven to be an insurmountable divide between technology and educational science in the past. It sheds light on knowledge, learning, and action from the perspective of social science action theories and develops a holistic view of learning connected to the key concept of "expertise." A central category of this approach is the modern buzzword "interactivity," which Baumgartner and Payr redefine within the framework of their research. The authors demonstrate through a typology of educational software and a concrete case study on foreign language acquisition that their learning model can be utilized for both theoretical engagement and didactic practice. As a result, this book is also relevant for teachers who wish to enrich their lessons through the use of software, providing valuable suggestions, insights, and reflective approaches. Contents include: Knowledge and Learning, Learning and Action, Learning as Process and Paradigm, Interactivity and Software, Software Typology, Foreign Language Acquisition and Learning Model, Software Critique.
