How Important is Teacher Content Knowledge?

Room to Grow - a Math Podcast

In this episode of Room to Grow, Joanie and Curtis host special guest Dr. Katey Arrington to discuss the importance of teacher content knowledge.
Dr. Arrington is the Associate Director of the UTeach Institute at the University of Texas at Austin. She is also serving in the Presidential line for NCSM: Leadership in Mathematics Education from 2022-2026. Previously, she led the K-12 system services work at the Charles A. Dana Center, served as a mathematics coordinator for a growing, diverse district in Texas, instructional coach, and taught in both K-12 and community college systems. Katey earned a Ph.D. in Educational Policy and Planning, Master of Arts in Mathematics Education, and Bachelor of Science in Mathematics. She has extensive experience in leading networks for growing impact and designing and implementing system-level change for increasing equitable outcomes.
Early on in the conversation, it is agreed that caring about students in a non-negotiable and important component of effective teaching, but caring without math content knowledge is not likely to result in student learning. Our hosts and their guest explore the ideas of pedagogical content knowledge, math content for teaching, and approaching mathematics as ways of thinking, not just ways of getting answers. Expanding learning is presented as a group endeavor, but also something a teacher can pursue on one’s own.
We encourage you to explore the resources below, referenced in this episode:

• The Developing Mathematical Ideas (DMI) professional learning program
• Numberphile on You Tube is one of Curtis’ favorite sources to explore mathematical curiosity
• The Coherence Map from Student Achievement Partners on the Achieve the Core website provides a clickable visual map of how content standards connect and build on one another
