The adaptation takes place in modular OER units (Articulate Rise), which can be used flexibly in an international context. Existing materials are expanded, linguistically and culturally adapted, and didactically realigned. Particular emphasis will be placed on co-creation between the German and Ukrainian teams, ensuring that the OER reflects diverse European teacher education contexts. In addition, workshops for testing and feedback loops with teachers and students are planned. All of this is implemented in a collaborative working method that focuses on co-creation.
