Nanette Seago

For more than 20 years, Nanette Seago has designed, developed, and researched secondary mathematics professional development materials.

Seago serves as Senior Program Associate for the Mathematics team at WestEd. She is the principal investigator (PI) for Video in the Middle: Flexible Digital Experiences for Mathematics Teacher Education, funded by the National Science Foundation (NSF) and co-PI for NSF-funded investigations of the impact of professional development on implementation of geometry teaching practices. She was the PI for Learning and Teaching Geometry: Videocases for Mathematics Professional Development and co-PI for an efficacy study focused on learning and teaching linear functions.

Seago has over 30 publications, which include video-based professional development materials, a book and book chapters, and articles. She is primary author of Learning and Teaching Linear Functions and Learning and Teaching Geometry, video-based resources designed to better equip teachers to prepare and implement lessons that will help students develop conceptual understanding of linear functions.

Seago collaborated with LessonLab in the development of the TIMSS-R public release videos and the design of an online course, TIMSS Video Studies: Explorations of Algebra Teaching, sponsored by Intel Corporation.

She cowrote Examining Mathematics Practice Through Classroom Artifacts and cowrote a chapter for Mathematics Teacher Noticing: Seeing Through Teachers’ Eyes.

Seago received a bachelor’s degree from the University of California, Los Angeles; a teaching credential from California State University, San Bernardino; and a mathematics supplemental authorization from the University of California, Riverside.
