This paper is a commentary on the theoretical formulations of the five empirical papers in this special issue. All five papers use aspects of the theory of commognition as presented by Anna Sfard; however, even when the same notions (e.g., rituals or explorations) are incorporated into theoretical frameworks undergirding the research, these notions are not always used in the same way. The analysis of how commognitive theory is used in the papers suggests that it is broad enough to be a useful theoretical lens in diverse settings. However, there are many aspects of Sfard's careful theoretical formulation that are not touched upon, suggesting that there is much more potential for use of the theory than has been realized in these papers.
