This document discusses the teaching-research nexus and its impact on student learning and teaching practices. It differentiates between teacher research, action research, and classroom research. Teacher research involves teachers conducting research within their own classrooms. Action research pursues both action, or change, and research simultaneously to improve practices. Classroom research focuses on inputs and outputs within the classroom setting. The document provides examples of these types of research and outlines their benefits, which include improved teaching, better student outcomes, and improved teacher confidence through evidence-based practices. Key aspects of action research design and processes are also summarized.
