In the Project Data Science and Big Data in Schools (ProDaBi), we are developing, implementing, and evaluating how data science, big data and artificial intelligence can be taught in schools. Since the 2018/2019 school year, the Paderborn University (Didactics of Mathematics, Didactics of Computer Science) has been conducting a project, initiated and supported by the Deutsche Telekom Stiftung, for developing and researching curricula for grades 5-13 and related teacher training courses .
