Sarah Warner

Sarah Warner is a Research Associate in WestEd’s Science, Technology, Engineering, & Mathematics program, where she specializes in studying student and teacher learning within mathematics classrooms.

Warner contributes to the development and research of mathematics curricula and teacher professional development, including WestEd’s Making Middle School Mathematics Accessible to All Students project and the National Research & Development Center on Cognition & Mathematics Instruction.

She also conducts mathematics and science education evaluation projects, such as the national evaluation of the Intel Math professional development program, and the evaluation of the Earth and Space Science Partnership at Pennsylvania State University. The latter project is an MSP grant that was extended from 3 years to 5 years, in part due to the positive impact documented by the evaluation.

Warner coauthored WestEd’s Making Mathematics Accessible to English Learners: A Guidebook for Teachers. This bestselling guidebook helps middle and high school mathematics teachers reach English learners in their classrooms.

Prior to joining WestEd in 2008, Warner was a Research Assistant for the Mathematics Learning and Teaching division at Education Development Center, Inc. There she wrote lesson plans for Think Math!, a research-based elementary mathematics curriculum funded by the National Science Foundation.

She has taught mathematics to elementary, middle, and high school students at all levels of achievement and in school and after-school settings. Warner has presented nationally at education conferences and symposia.

Warner received a BS in mathematics from Bates College and an MA in mathematics education from the University of California, Berkeley.
