Triantafillou, Chrissavgi; Spiliotopoulou, Vasiliki; Potari, Despina – International Journal of Science and Mathematics Education, 2016
The present study explores reasoning and argumentation in Greek mathematics and physics texts in specific topics related to the notion of periodicity. In our study, argumentation is taken as the sequence of the modes of reasoning (MsoR) that an author develops in a text when organizing and presenting new knowledge. Inductive content analysis was…
