Within the framework of the Covid-19 pandemic, we develop digitization strategies for education, such as the TEDDY program (Experiential Development of Digital Competences for Teachers in English). This focuses on the digital skills that secondary school teachers need and have developed over the course of the crisis. TEDDY aims to train and support teachers (in the Climate-KIC Young Innovators programme) to work with digital tools for sustainable development, during and after the pandemic, in order to improve the learning experience of their students. .
