Overherd: designing information visualizations to make sense of student's online discussions

Libby Hemphill, Stephanie D. Teasley
2010 International Conference of the Learning Sciences  
Overherd is an information visualization tool that makes patterns of interaction and activity in online discussion boards visible so that instructors can more easily analyze their students' contributions. Our system uses the forums tool from the Sakai learning management system (LMS) to create visual representations of online behavior. We describe the design and development of Overherd, and provide design recommendations for "mashups" that extend the functionality of LMS yet rely on existing data within these learning environments.
