This project builds on two prior SGER grants, which produced respectively a text mining tool bench called TagHelper tools (Rosť et al., 2008) (subsequently the LightSIDE toolbench (Mayfield & Rosť, in press)) and an architecture for managing heterogeneous teams online consisting of multiple humans and one or more intelligent conversational agents, originally called Basilica (Kumar & Rosť, 2011), now called Bazaar (Adamson & Rosť, 2012). These tools form the foundation for the emerging research area of dynamic support for online collaborative learning as well as assessment of learning processes in groups and dyads interacting face to face (Gweon et al., 2011; Gweon et al., 2012; Jain et al., 2012). PI Rosť has received two awards and several additional award nominations at a variety of HCI and Learning Sciences conferences for this work. Under this grant and synergistic funding, both tools have been substantially extended and used together in a series of over a dozen successful studies of high school and college level engineering, science and math learning (with pre to post test gains on assessments designed by course instructors) (e.g., Chaudhuri et al., 2009; Kumar et al., 2010; Ai et al., 2010; Kumar et al., 2011; Dyke et al., 2012; Howley et al., 2012), one study of group decision making (with an assessment of constructed plan quality using a rubric validated by the Navy used as a validation) (Kumar, 2011), and two completed PhD dissertations (Kumar, 2011; Gweon, 2012). Typical effect sizes reported in published work validating the approach are on the order of .5 to 1.25 standard deviations, which are considered medium to large effect sizes. In addition, TagHelper and LightSIDE are both used as learning tools in applied machine learning and introductory computational linguistics courses at Carnegie Mellon University and abroad. All tool benches produced with this funding are freely available for research purposes. Cumulatively, LightSIDE and TagHelper have a user base of several thousand users in 75 countries.
