Relations Between Policy and Practice: A Commentary

Abstract: The research reported in the cases suggests that California’s new policy has affected instructional practice. Many teachers have tried to change their mathematics teaching, and some have made significant changes. But practice also has had a profound influence on the new policy. The teachers in the cases did not simply assimilate new texts and curriculum guides. They enacted new instructional policies in terms of their inherited beliefs, knowledge, and practices. Hence when teachers changed in response to the policy, they did so in terms of their pre-existing practice, knowledge, and beliefs. They reframed the policy in terms of what they already knew, believed, and did in classrooms. The result in many classrooms was a remarkable melange of old and new math teaching. This may be only the beginning of the story of the California math framework. It remains to be seen whether the reform will continue, and, if it does, whether the California system will be able to support this reform adequately.

Instruction, Capacity, and Improvement

Abstract: Since World War II, efforts to improve schools have numbered in the thousands. Most efforts have concentrated on improving the curriculum materials used in schools or on "training" teachers in new instructional methods. Many of these efforts have gone under the banner of "building instructional capacity," a term that for decades has been featured prominently in conversations about educational reform. Unfortunately, three decades of research has found that only a few interventions have had detectable effects on instruction and that, when such effects are detected, they rarely are sustained over time. A review of research and professional experience with school improvement suggests several explanations for these disheartening findings. One is that schools are complex social organizations situated within, and vitally affected by, other complex social systems including families, communities, and professional and regulatory agencies. The larger social environment of schools constrains and shapes the actions of teachers, students, and administrators, often in ways that greatly complicate the work of school improvement. Challenges to school improvement are particularly acute in highpoverty settings where recruiting wellqualified teachers is difficult and where the emotional and health problems of students often deflects attention to educational issues or impedes work on them. As a result, many researchers now believe that school improvement involves much more than efforts to change interactions occurring within schools. To succeed, school improvement interventions also must attend to the complex relationships that exist among intervention agents, schools, and their social environments.
