Episode 2502: Discussing the Science of Math - Sarah Powell and Rachel Lambert
Sarah Powell, a professor at the University of Texas, leads the Science of Math initiative, aiming to enhance math education through evidence-based practices. Rachel Lambert from UC Santa Barbara critiques this initiative, raising concerns about current methodologies and the interpretation of instructional claims. They explore the importance of balancing procedural fluency with conceptual understanding in math, discuss misconceptions about algorithms, and advocate for higher citation standards in educational research. Their insights provide a thought-provoking dialogue on improving math instruction for all students.
