In the December 2010 issue of the American Educational Research Journal (vol. 47, no. 4, 919-963), authors Chrysan Gallucci, Michelle DeVoogt Van Lare, Irene H. Yoon and Beth Boatright present "Instructional Coaching - Building Theory About the Role and Organizational Support for Professional Learning". HyperRESEARCH was utilized to code all the interviews for this study.
The abstract conveys that "Instructional coach initiatives aimed at teachers' professional development are expanding in reforming school districts across the United States. This study addresses the lack of research regarding the professional development of instructional coaches. Drawing on sociocultural learning theory, specifically a model called the Vygotsky Space, the authors use a case approach to examine the learning experiences of a single secondary literacy coach. Hypotheses suggest that (a) coaches are not unproblematic conduits of reform ideas but are also learners of new content and pedagogy; (b) as coaches' conceptual development about instruction grows, their ability to coach also matures; and (c) professional development that supports coaches is best aligned around a workplace pedagogy that addresses the learning needs of multiple system actors."
