Level 1: sharing/comparing of information Level 2: the discovery and exploration of dissonance or inconsistency among ideas, concepts or statements Level 3: negotiation of meaning / co-construction of knowledge Level 4: testing and modification of proposed synthesis or co-construction Level 5: agreement statement(s) / applications of newly constructed meaning Facilitating and analysing roles in computer supported collaborative learning • EARLI 2007 Symposium Bram De Wever, Tammy Schellens, Hilde Van Keer, & Martin Valcke • Ghent University
