The multi-site study was conducted during the 2004-2005 and 2005-2006 school years in three large urban school districts from three states: California, Pennsylvania, and Virginia. A total of 81 first grade teachers and their 468 students from 19 Reading First schools formed the analytic sample in the study. Classrooms observations of teaching practice showed significant improvements in TSG schools: TSG teachers scored .86 standard deviations higher on the comprehension measure and .58 standard deviations higher on the vocabulary measure than control teachers. TSG teachers also significantly outperformed control teachers on the teacher knowledge measure of vocabulary instruction (ES = .73) . Confirmatory analysis of student outcomes focused on passage comprehension, reading vocabulary, and oral vocabulary; of these only the latter was marginally significant ( .44) . Implications for teacher practice and future research are  \ndiscussed.  \n5  \nIntroduction  \nFor almost two decades, research on professional development has suggested that commonly used one or two day trainings, that is, one-shot in-services, are ineffective (Goldenberg & Gallimore, 1991) . Large-scale case study research (e.g. , Huberman & Miles, 1984) and survey research (Garet, Porter , Desimone, Birman, & Yoon, 2001) suggest that teachers value continuous coherent training opportunities that integrate teacher learning into daily classroom instruction. Fundamentally absent in the short term , and typically large scale, professional development workshops are opportunities for teachers to collectively reflect on the relevance of something before they learn it, obtain new knowledge in real contexts, and connect new ideas and skills to their already diverse teaching experiences (Knowles, Holton, & Swanson, 2005) . Although professional development that contains solid conceptual and theoretical material tends to be viewed more positively, teachers crave training opportunities that contain concrete examples relating to their current curricula (McLaughlin, 1990) .  \nIn recent years there has been an increased interest in the use of the Teacher Study Groups (TSG) or the Teacher Work Group as an approach to professional development (Carroll, 2005; Lambert, 2002; Meyer et al. , 1998; Murphy, 1992; Saunders et ","cbCaisJ4iQ43eJ6O","https://ap.wps.com/l/cbCaisJ4iQ43eJ6O","pdf",570370,59,"English","# Abstract\n# Introduction\n# Method\n# Results\n# Summary and Conclusions\n# References\n# Appendix A\n# Appendix B","[{\"question\":\"What does the Teacher Study Group (TSG) aim to improve in first grade classrooms?\",\"answer\":\"TSG is designed to help first grade teachers use research-based instructional strategies by integrating TSG content into their existing curriculum.
