in the classroom may advance understanding of the science of learning in important and useful ways.
Taken together, these latter two suggestions imply that the links between research and practice should routinely flow in both directions. The insights of researchers help shape the practitioner’s understanding, and the insights of practitioners help shape the research agenda and the insights of researchers. Moreover, the link between each of the arenas and the knowledge base flows in both directions. Efforts to align teaching materials, teacher education, administration, public policy, and public opinion with the knowledge base are part of an ongoing, iterative research effort in which the implementation of new ideas, teaching techniques, or forms of communication are themselves the subject of study.
The agenda that follows proposes research and development that can help consolidate the knowledge base and can build the two-way links between the knowledge base and each of the arenas that influences practice. But that knowledge base is also fed by research on learning more generally
