Communicating data exploration insights through posters -A preliminary analysis of primary students´ learning outcomes

International audienceSince data and its representations have gained a significant role in our society, mathematics education has to adapt by finding ways of teaching students statistical literacy from primary school onwards. In a teaching unit that was designed as part of a bachelor´s thesis, students of a fourth grade (10 to 11 years old) were introduced to group comparisons with the help of TinkerPlots and asked to create posters on statistical mini-projects. This paper aims at providing first ideas for a framework for the analysis of such means of communication to understand what results the young students communicate and how they do so. The posters show that the primary school pupils already employ not only local perspectives but utilize more global views to interpret the data
