Digital media and tools – e.g. interactive computer simulations or digital learning journals – offer great opportunities for successful digitally-supported learning in schools. However, this presupposes that they are integrated into the lessons in a didactically meaningful way and that they actually stimulate thinking and working processes in students that are conducive to learning. In the graduate school “Digitally Supported Teaching-Learning Settings (Di.ge.LL)”, practical and research-based digitally supported teaching-learning environments as well as digital tools for planning and organizing lessons for teachers are therefore being developed and their effects are examined in several research phases. Interdisciplinary teams of researchers from general and subject-specific teaching-learning research (from the University of Education Freiburg and the University of Freiburg), who have been working on digitally supported teaching for many years, are collaborating in the graduate school. Involved in the development and research are, among others, expierenced teachers with an interest in a scientifically-oriented career (as future researchers at universities or professional development facilitators in schools), who are further qualified in a structured study program. The school also works closely with regional teacher training and school supervision in order to make experiences and results usable for practice and professional development from the very beginning.
