A Complexity Analysis of Two Teachers’ Learning from Professional Development

Abstract

Professional development is widely viewed as a key lever for school change. Each year, federal and state governments pour billions of dollars into developing teachers, while researchers seek to identify which professional development programs are most effective. However, even as consensus has been growing in the research and policy communities about what constitutes high-quality professional development, teachers continue to vary greatly in what and how much they learn through such programs. There is no theory of teacher learning that explains this variation. In this dissertation—a comparative case study of two teachers from the same school who were participating in the same professional development initiative —I used complexity theory as a lens to understand teacher learning as a complex system. The intention was to develop causal explanations of teacher learning that accounted for the interactions between a particular teacher, a particular school, and a particular professional development. Data analysis revealed that whether, what, and how the teachers learned through professional development was contingent upon learning conditions that resulted from three intersecting systems: the teacher, the school, and the professional development. Although they were colleagues, the two teacher participants experienced professional development under different learning conditions, resulting in different learning outcomes; one teacher changed little, while the other ultimately transformed some of her beliefs and classroom practices. I found seven structural elements, across the three system levels, that shaped the system of teacher learning. Based on my analysis, I propose an analytic framework that can be used to analyze the conditions within and the interactions between the three systems. By offering a new means to analyze professional development through a complexity lens, this study contributes to a broader understanding of teacher learning. There are also important implications for designing and selecting professional development that will meet the needs of individual teachers in specific school contexts.
