This collection of video lessons from Inside Mathematics at the University of Texas at Austin is a valuable resource for educators striving to enhance their mathematics instruction. It addresses the challenge of sharing effective teaching practices by providing access to tested public lessons, reflective mathematics practice tours, and various teaching tools. Stemming from the Noyce Foundation’s Silicon Valley Mathematics Initiative (SVMI), Inside Mathematics promotes high-performance expectations, ongoing professional development, and improved math instruction. The initiative emphasizes formative and summative performance assessments, pedagogical content coaching, and leadership training. This collection of resources fosters a professional learning community where educators can share insights, resources, and experiences, breaking the barriers that often isolate struggling teachers. It encourages collaboration, reflection, and continuous improvement in mathematics teaching and learning practices.
