Moderation of Students' Activities in Co-located Computersupported Collaborative Learning using Digalo

چکیده
Digalo is a graphic-based software tool for supporting collaborative argumentation and structured discussion. It has been developed in the framework of the DUNES project (IST-2001-34153, http://www.dunes.gr ). Using Digalo consists of synchronously co-creating maps built of written notes inside different cards (represented by diverse geometrical shapes), as well as using different arrows to represent various types of connections between the cards or contributions. These ‘cards’ and ‘arrows’ represent the ontology or the ”grammar” of the discussion, which constrains but also facilitates and promotes the discourse [1,2] by guiding the learners to use specific speech acts and raising their awareness to their discursive roles, thus encouraging a certain type of discussion, such as critical dialogue.
