We present a study of human tutorial dialogues in a core Computer Science domain that: focuses on individual tutoring sessions, rather than on contrasting different types of tutors; uses multiple regression analysis to correlate features of those sessions with learning outcomes; and highlights the effects of two types of tutor moves that have not been studied in depth so far, direct instruction and positive feedback.
