New common standards for mathematics were adopted by most of the states in the US by 2010. Achieving these standards, however, is a challenge, since they require significant changes in how mathematics is taught. Lesson study ("jugyou kenkyuu") is a form of professional development that has been credited for supporting profound changes in…

Background/Context: School districts are increasingly expected to support students in meeting ambitious mathematical learning goals. Many schools and districts are investing significant resources in the provision of time for teacher collaboration in the hope that this will help teachers improve their instruction in ways that support students in…

My Teaching Partner-Secondary (MTP-S) is a web-mediated coaching intervention, which an initial randomized trial, primarily in middle schools, found to improve teacher-student interactions and student achievement. Given the dearth of validated teacher development interventions showing consistent effects, we sought to both replicate and extend…

Research has been showing that the most important development in K-12 education over the past decade has been the emergence of a growing number of urban schools that have been convincingly shown to have dramatic positive effects on the achievement of disadvantaged students. Those with the strongest evidence of success are oversubscribed charter…

This article presents an analytical approach for documenting the identities for teaching that mathematics teachers negotiate as they participate in 2 or more communities that define high-quality teaching differently. Drawing on data from the first 2 years of a collaboration with a group of middle school mathematics teachers, the article focuses on…

President William Jefferson Clinton is often credited with beginning a new era of improving teacher quality.
