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

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 behavioro Personalized agents increase supportiveness and help exchange

between students (Kumar et al., 2007b)o Agents are more effective when students have control over timing of

the interaction (Chaudhuri et al., 2008; Chaudhuri et al., 2009)o Agents that employ Balesian social strategies are more effective than

those that do not (Kumar et al., 2010; Ai et al., 2010)o 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)
