NRCSL's expanding connection with practice reflects the advancement of the field of cognitive research. With the formative theory of knowledge construction well established, research has been able to turn increasingly to the development and study of reforms based on that theory. Because successful classroom reforms cannot proceed without addressing realities that only classroom teachers confront and fully understand, collaborations have become indispensable to the work of education research. At NRCSL, therefore, the ultimate aim of research is threefold: to provide a scientific base for education reform; to take the lessons gained from implementation back to the laboratory for further theoretical study; and to attend closely to every issue and question that arises in the intermediate stages of work--the invention, testing, piloting, and refinement of new classroom methods.
