Common Core’s new math standards “have the potential to improve average student achievement” by adding focus, rigor and coherence, predict William H. Schmidt and Nathan A. Burroughs in the new American Educator.
Common Core State Standards in math resemble the high-quality standards of high-achieving nations, they conclude.
Furthermore, states with standards similar to CCSS-M had the highest eighth-grade mathematics score on the 2009 NAEP. “The more similar the standards were to the CCSS-M, the higher student achievement.”
