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…

Kospentaris, George; Vosniadou, Stella; Kazic, Smaragda; Thanou, Emilian – Frontline Learning Research, 2016
We argue that there is an increasing reliance on analytic strategies compared to visuospatial strategies, which is related to geometry expertise and not on individual differences in cognitive style. A Visual/Analytic Strategy Test (VAST) was developed to investigate the use of visuo-spatial and analytic strategies in geometry in 30 mathematics…
