Until recently, existing research on teacher professional development (PD) has largely relied on teacher perceptions and self-reports to evaluate effectiveness. Though more current research has used a diverse array of designs and methodologies to examine impact on teacher knowledge, practice, and student learning, uncertainty regarding the effectiveness of various PD models remains, particularly for these nonperceptive variables. There has been a call in the field to apply a consistent conceptual framework in order to identify critical mechanisms underlying effective models and to support improved theorizing about teaching and learning. Thus, we present an integrated literature synthesis of one collaborative model of PD, teacher study groups (TSGs), in an effort to make sense of the relatively rich body of research that has been performed on this model. We identified 32 studies that examined TSGs’ impact on teacher and student outcomes and synthesized this research using Desimone’s five-factor conceptual framework, which is being increasingly applied across the field. Findings suggest that TSGs are an effective PD model and that there are components of the model not accounted for in the five-factor framework that affect teacher outcomes and student learning. We conclude with a discussion of implications, including limitations of the five-factor framework and ideas for further refinement that situate PD in a vast empirical landscape.
