Action research is a type of descriptive research conducted by educators that pursues both change and understanding through a cyclical process of action and critical reflection. It is grounded in constructivism and supports the scholarship of teaching. The process involves looking at a situation by gathering data, building an understanding, thinking about causes and effects, planning and implementing an action, and evaluating the results. Tools used include experimental and quasi-experimental designs, triangulation of quantitative and qualitative methods, and grounded theory. Conceptual frameworks and data from multiple sources should guide analysis and decisions about teaching and learning.
