Many European and non-European countries, such as Germany, are racing into a momentous educational catastrophe almost unchecked: a competence catastrophe. Instead of nurturing learner competencies, such as creativity and self-directed learning, some educational organizations continue to favor traditional forms of learning, even in the face of digitization, employing what the author refers to as mediation logic that has no backing from modern research evidence in neuroscience and learning research. If the competence catastrophe can be stopped at all, then a courageous train of thought, such as that of Rolf Arnold presented in this book, requires implementation in pedagogical practice!

The concept presented in this book by Rolf Arnold provides, among other things, important foundations for understanding the development of diversity competence in education: A self-organized development process facilitated through an enabling educational framework. Doubts, contradictions and confusions are addressed in this book, which promotes an educational framework that targets competence development, including understanding the didactical process of assisting learner competence to systematically cope with the experience of experiencing, but also wider competencies such as the ability to cope with cognitive, but also emotional dissonance.
