edge of teachers, subject it to testing, and make those results available to be publicly shared and scrutinized.

And finally, to ensure quality oversight, the SERP research would be subject to both internal and external scrutiny and critique.

The work we propose here has the potential to substantially improve the knowledge base to support teaching and learning by pursuing answers to questions at the core of teaching practice. It calls for a linking of research and development—of instructional programs, assessment tools, teacher education programs and materials—that is now rare. It would bring research to bear on the problems of educational practice. And just as importantly, it would bring the problems of practice to the agenda of research.
