This comparative case study explores the agency of two teacher leaders (TLs) as they facilitate their respective teacher-organized lesson study groups. Applying sociocultural theory, I describe TL agency as manifesting at two levels: (1) the meanings teachers make about student learning, teaching, and teacher learning and (2) their talk and actions as facilitators of teacher learning during lesson study. I find that differences in each TL’s meanings of teaching and learning contribute to different approaches to facilitation and ultimately, different opportunities to learn for the teachers in each group, despite a very similar lesson study design and context. One TL’s meanings of teaching and learning demonstrate a strong and cohesive vision of instructional improvement that reflects constructivist shifts in mathematics education and emphasizes deepening understanding of the connections between ideas and/or strategies. Her facilitation shapes opportunities to learn characterized by engaging in the resolving of dissonances between new and prior understandings. The other TL’s meanings of teaching and learning reflect a fusion of traditional and constructivist approaches to teaching and learning, where exploration of multiple tools and strategies is valued, but primacy remains on the outcome of correct solutions. Her facilitation does not shape opportunities to learn characterized by deepened understandings or shifts in meanings of teaching and learning. Policy implications for supporting TLs’ agency in collaborative learning will be discussed. / A Dissertation submitted to the Department of Educational Leadership and Policy Studies in partial fulfillment of the requirements for the degree of Doctor of Philosophy. / Spring Semester 2019. / March 25, 2019. / Agency, Collaborative Professional Learning, Lesson Study, Teacher leaders / Includes bibliographical references. / Motoko Akiba, Professor Directing Dissertation; Jeanine Turner, University Representative; Ayesha Khurshid, Committee Member; Stacey Rutledge, Committee Member.
