Exploring model-supported coordination processes in PSMIs with micro-level video data

Micro-level analyses of participant interactions with models are needed to gain insight into the ways in which coordination processes unfold during PSMIs. This study uses micro-level video-based analysis to understand how multiple modalities are employed by three dierent groups of participants during a PSM workshop to create, structure and change shared action spaces. Joint aordances in the course of
the PSMI are studied to explore how communicative understanding is developed and sustained in model-supported collective reasoning processes. The observed diversity in social and informational quality of model-supported interactions suggests that a nuanced view of microlevel coordination processes in PSMIs is needed.
