Proportion in geometry: a reference model for textbook analysis

Status seminar with Dyana Wijayanti

Abstract:

The aim of this seminar is to share the progress of my research since November 2013. As part of the mandatory status seminar, I also discuss my further research plan. Furthermore, I also want to present my current work entitled “a praxeological reference model in the case of proportion in geometry ”.  The focus of this current work is on Indonesian lower secondary textbooks and national examination task. After having established, in my last study, that praxeological reference models can be used to analyse proportion in the arithmetic domain, I now study how two domains can be analysed and connected, using praxeological reference models.
