This presentation is part of a Ph.D. project that aims to increase knowledgeabout how to support the development of teacher students’ pedagogical contentknowledge (PCK) for teaching statistical inference. Dealing with the existingdiversity of theoretical approaches is a well-known challenge for the researchcommunity. The focus of this short presentation is to compare two reputable frameworks: Mathematical knowledge for teaching (MKT) and Refinedconsensus model (RCM) for pedagogical content knowledge. This comparisonwill highlight their contributions, merits, shortcomings, and possible connections to evaluate and guide an ongoing teaching and learning design in teachereducation for primary school.
