This study investigated the extent to which the sociomathematical and professional norms intentionally fostered through the use of the video-case curriculum materials in an early mathematics pedagogy course re-emerged in a similar context, but with different cohorts: (a) at the end of the university teacher preparation program and (b) during a professional development session for graduates of the program. This study revealed that the three sociomathematical norms that were introduced in the early pedagogy course—naming and comparing, mathematical argument, and pushing understanding. Four professional norms were also exhibited by both groups, but with more variation. These norms were listening, critical yet respectful norm, tentative stance and evidence.
