  2. Developing technology capable of shaping conversation and supporting effective participation in conversation to achieve positive impact on… Human learning Health Wellbeing

  3. Automatic Analysis Of Conversation Positive Learning Outcomes Conversational Interventions

  4. Computer Supported Collaborative Learning ** Students learn up to 1.25 standard deviations more when interactive support is provided in the environment. (more than a full letter grade!)

  5. 7 Years of Positive Results • Foundational study: students work with a partner and dialogue agent for support Learn 1.24 s.d.more than individuals without support (Kumar et al., 2007a) • Selected results inform iterative design of agent behavior • Personalized agents increase supportiveness and help exchange between students (Kumar et al., 2007b) • Agents are more effective when students have control over timing of the interaction (Chaudhuri et al., 2008; Chaudhuri et al., 2009) • Agents that employ Balesian social strategies are more effective than those that do not (Kumar et al., 2010; Ai et al., 2010) • Students are sensitive to agent rhetorical strategies such as displayed bias (Ai et al., 2010), displayed openness to alternative perspectives (Kumar et al., 2011), and targeted elicitation (Howley et al., 2012) • Bazaar architecture enables efficient, principle based agent development (Kumar & Rosé, 2011; Adamson & Rosé, 2012)

  6. Sociolinguistics Language Use Computational Models Of Discourse Analysis Discourse Analysis Machine Learning Language And Identity Applied Statistics Multi- Level Modeling
