This study reports the impact of high sensitivity to early exchange in 11th-grade, CSCL
triads solving well- and ill-structured problems in Newtonian Kinematics. Analysis of the
evolution of participation inequity (PI) in group discussions suggested that participation levels
tended to get locked-in relatively early on in the discussion. Similarly, high (low) quality member
contributions made earlier in a discussion did more good (harm) than those made later on. Both PI
and differential impact of member contributions suggest a high sensitivity to early exchange; both
significantly predicting the eventual group performance, as measured by solution quality.
Consequently, eventual group performance could be predicted based on what happened in the first
30-40% of a discussion. In addition to theoretical and methodological implications, implications
for scaffolding CSCL groups are drawn.
This paper was presented at the 7th International Conference on Computer Supported Collaborative Learning (CSCL), held in New Jersey, USA from 16 - 21 Jul 2007
