Sasha Wang - Böcker

SashaWang revisits the van Hiele model of geometric thinking with Sfard’s 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 Sfard’sframework 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.
