This study examined the effects of coaching with versus without demonstrations of evidence-based book-reading practices on teachers' use of strategies during independent book-reading periods. A total of 22 Head Start teachers were randomly assigned to one of two cohorts. One cohort (n = 12) participated in biweekly coaching sessions that included having coaches demonstrate how to incorporate a focus on key literacy skills while reading books aloud to students (C + D); the other cohort (n = 10) participated in coaching sessions that did not include explicit demonstration and modeling of evidence-based book-reading practices (C-only). Postintervention observations revealed that teachers in the C + D cohort engaged in behaviors and interactions during their book reading that focused on phonological awareness, alphabet and word knowledge, and print and book awareness to a greater extent than did teachers in the C-only cohort. Cohort differences were also found during an observed small-group activity and on the language and literacy items of a general measure of the classroom literacy environment. Results lend support for the importance of demonstration and observational learning as dimensions of coaching to bring about significant change in teachers' literacy-enhancing practices.
