Layering methodological tools to represent classroom collectivity

Our research is guided by the question: “How might we observe, document, display, and analyze data from a collective systems perspective?” In this research forum, we share new research tools for studying mathematics classrooms, highlight opportunities for observation and analysis by layering these tools, and then illustrate how the layering of tools allows for visual distinctions across lessons and classrooms.
