SashaWang revisits the van Hiele model of geometric thinking with Sfards discursiveframework to investigate geometric thinking from a discourse perspective. Theauthor focuses on describing and analyzing pre-service teachers geometricdiscourse across different van Hiele levels. The explanatory power of Sfardsframework provides a rich description of how pre-service teachers think in thecontext of quadrilaterals. It also contributes to our understanding of humanthinking that is illustrated through the analysis of geometric discourseaccompanied by vignettes.TheoreticalBasis: The van Hiele Model.- Theoretical Framework: Learning as Communicating,Sfards Discursive Framework, and the Levels of Geometric Discourse.- Methodology:Participants, the van Hiele Geometry Test, Interview Tasks.- Data Collectionand Analysis.- Results from the van Hiele Geometry Test and One-on-OneInterviews.- Changes in van Hiele Levels and Changes in Geometric Discourse.Dr.Sasha Wang is an assistant professor of mathematics education at the BoiseState University, Idaho, United States.
