We describe a system for producing automated professional mentoring using a quantitative model of enculturation. We are developing an automated mentoring technology, AutoMentor, that builds on previous research on automated tutoring systems, specifically on AutoTutor, a computer tutor that helps students learn about science and technology topics by holding(More)

However, the faculty and staff effort and physical resources required for the number of students enrolled can be daunting and affect the quality of instruction. To reduce these costs, ensure a high quality educational experience, and reduce variability in student outcomes(More)

This study examined the interactions between players and mentors in one epistemic game, Urban Science. Using a new method called epistemic network analysis, we explored(More)
