The goal of making sustainable development a reality in the 21st century continues to be a complex, global challenge that cannot be met with linear ways of thinking and drawing conclusions. Instead, ecological, economic, socio-cultural and political factors must be considered in an interconnected way when analyzing problems. To promote these and other competencies of an education for sustainable development, an interactive learning environment was developed for school and out-of-school learning, so-called Reflectories. In this article, the theoretical basics as well as concrete implementation possibilities for dealing with the goals of sustainable development in order to promote the corresponding competencies are presented. Furthermore, an insight into the first evaluation results is given.
