Eye-teach-stats aims to support pre- and in-service mathematics teachers in (further) developing their statistical PCK and CK. These knowledge facets are required if teachers are expected to prepare their students to become data literate citizens of civil society. Thus, we aim to provide teachers with innovative and effective learning opportunities to (1) diagnose and (2) deal with students' statistical (mis)interpretations as well as to (3) overcome their own statistical difficulties.
