The book "Knowledge Management in School Development" by Kaja Heitmann examines how knowledge management, developed in the business sector, can be applied to the specific requirements and challenges of schools. From a systems theory perspective, the author analyzes the organization of schools and highlights their particularities in comparison to business enterprises. The resistance to change in schools is addressed, and it is demonstrated how knowledge management can be linked with established approaches to school development. Through empirical studies, theoretical insights are confronted with practical experiences in schools. The exploration of typical ways of handling data, information, and knowledge in schools, as well as the identification of barriers and prerequisites for the implementation of knowledge management, provides valuable insights for the practice of school development.
