Guru models the strategies and dialogue of expert human tutors and is a logical progression from AutoTutor, which models novice human tutors. The Guru expert tutor, by using expert human tutor strategies, actions, and dialogue, should promote larger learning gains than previous novice computer tutors. Guru could have a big impact on Memphis City Schools because it is designed to improve educational outcomes on the Tennessee Gateway Science Test, which high school students must pass to receive a diploma.
