This document discusses action research as a methodology to bridge the gap between theory and practice. It provides a brief history of action research, noting that Kurt Lewin is generally regarded as the first to use the term in the 1940s. The document defines action research as aiming to contribute to practical concerns and social science goals through collaboration. It argues that action research involves practitioners and researchers working together through a cyclical process of identifying problems, planning actions, implementing plans, and evaluating results. The key features of action research are collaboration between researchers and subjects, and the active involvement of subjects as co-researchers.
