Neria, Dorit; Amit, Miriam – International Group for the Psychology of Mathematics Education, 2004
This research study deals with the modes of representation that ninth-graders choose in order to communicate their problem solving paths and justifications, and the relation between these modes of representations and achievement level. The findings are based on analysis of 350 answers to problems that demanded communication of reasoning,…
