“…As part of a literature review that preceded this study (Stillman & Anderson, 2009), we read more than 100 studies and research reviews (e.g., Clift & Brady, 2005;Hollins & Guzman, 2005;Sleeter, 2001), all of which focused on preservice teachers' clinical experiences and were published within the past 25 years. Much of this research focuses on the relationship between cooperating teachers and student teachers as a context for learning (e.g., Borko & Mayfield, 1995), but few studies-excepting those focused on professional development schools (e.g., Connor & Killmer, 2001)-address how contours of student teaching placements shape what preservice teachers learn about teaching. 4 Few look comparatively at how variations in context and cooperating teacher influence new teacher development or how multiple placements influence teacher learning over time (e.g., LaBoskey & Richert, 2002).…”
