Interactive Research and Development on Teaching (IR&DT) is an alternative Research and Development (R&D) strategy that probes the questions, problems, and concerns of classroom teachers in a nonlinear manner. Each of the primary functions of traditional R&D--research, development, dissemination, and implementation--are performed collaboratively by an IR&DT team composed of teachers, researchers, and trainer/developers, rather than in the standard R&D sequential ordering. This new approach limits the formation of diverse constituencies within the larger research group, and permits smooth implementation of research results into practical use. The collection of papers presented here examines a San Diego-based team's IR&DT and examines the consequences and effectiveness of this innovation. The effect of the strategy on personnel, data collecting, and educational policy makers is discussed. (LH)
