|Abstract:||Argumentative activity has been found beneficial for knowledge building and evaluation of information in some conditions. Many CSCL theorists have suggested that graphical representations may help in this endeavor. In the present study we examine effects of a graphical representation of synchronous discussions. 54 Grade 7 students from 2 classes participated. The study tested the effects of: (a) the use of shapes representing some argumentative functions in discussions and the use of arrows representing support/challenge between utterances; (b) the use of floor control to monitor turn taking during discussion. It appears that the combination of use of shapes and arrows and of the control over turn taking invites students to express more relevant claims and arguments, and less chat expressions.|
