Due to changes in the state curriculum of the German federal state of North Rhine-Westphalia, teaching statistics using graphic calculators, particularly for simulations, has become a focus of attention. This created a high demand for professional development (PD) courses in statistics. Considering this demand and approved concepts for learning and teaching statistics we created a PD course aimed at focusing on fundamental ideas and a pedagogically advantageous use of digital tools for simulations and interactive visualizations. Retrospective self-assessed questionnaires were used to measure the developments in participants’ content, pedagogical, and technological knowledge. Our analysis shows interesting findings regarding heterogeneity in gaining new knowledge, for example in respect to handling pupils’ misconceptions, didactically appropriate use of digital tools, or planning and conducting lessons.
