This study involved the analysis of the complex interactions that take place between tutors and preschool children using a computer during early literacy tutoring sessions. Eight five-year-old pre- and early-readers attending a childcare centre participated in daily 20-minute tutoring sessions for two weeks. The literacy software (a beta version) was especially designed to guide tutors while working one-on-one with elementary school students falling into the lower 30% of reading achievement (i.e., at-risk). Parent surveys, videotaped tutor/child sessions, independent observer data, and tutor reports yielded rich descriptions of the tutor/child/computer process. Rigorous grounded theory analyses generated three comprehensive themes: rapport, motivation, and scaffolding. The first focused on interpersonal issues, the latter two on teaching/learning. Implications for practice are discussed.
