UbiCoS: Supporting Peer Help-Giving Across Middle School Mathematics Contexts

by Erin Walker

Most intelligent tutoring systems for collaboration operate within the context of a single learning environment, but collaboration in the classroom operates across multiple platforms and contexts. We have built a system, called UbiCoS, that presents middle school mathematics students with three digital contexts for engaging in help-giving interactions: A synchronous discussion platform, an asynchronous Q&A forum, and a teachable agent. Our system predicts whether a given student will give effective help within each context, adaptively scaffolds them in giving help, and assigns badges for particularly productive interactions. Students engage with this system within the context of a Modelling Math curriculum that also promotes problem-based learning and active face-to-face discussion among peers. Our poster will describe the system and present results from classroom studies that show how the system influences student help-giving interactions.
