Drawing on literature since 1997, this review explores the effects of teacher induction on beginning teachers' conceptions and practice of teaching, and it identifies three approaches to understanding such effects, as found in the literature. The first approach addresses the assumed effects of teacher induction components on beginning teachers' teaching using theoretical assumptions as a base. The second approach analyzes the effects through teachers' self-reports. The third explores the effects of using multiple data sources. Although teacher induction affects beginning teachers' ideas about teaching, few studies capture its effects on teaching practice and student achievement. Thus, this review suggests directions for future research. (Contains 1 note.)
