As one of its institutional missions, the P.K. Yonge Laboratory School at the University of Florida focuses on the problem of utilization of research and development for the improvement of instruction. In an effort to reduce the time lag between the discovery of new information and the general adoption of practices based on that information, the School has developed a model for educational change which begins with problem identification and continues through classroom-based research to utilization of research results in the state public school system. Steps identified in this process are: (1) problem determination; (2) search of existing information for possible solutions; (3) formulation of a research project if no solutions already exist; (4) implementation of the project in the Laboratory School; (5) field testing and modification of the project in selected public schools; (6) compilation, publication, and distribution of a report to the state school system; (7) receipt of feedback from educators; (8) drive-in conferences and workshops for school personnel interested in implementing the project; and (9) maintenance services (consultation, sharing sessions, etc.) for schools using the project products. Activities of the Yonge Laboratory School since 1970, when research and development for public education was made its main mission, illustrate the fact that it has a workable model for utilizing research and development processes to improve instructional programs.
