Podcast: Karen Tzanetopoulos on the Science of Math Learning in Research and Practice

"In this episode of the Knowledge for Teachers Podcast, Karen spoke with host Brendan Lee, sharing how she started working out of an office that was like a janitor’s closet to quietly do her own structured literacy with students and how her interest in math began while working in the public schools, as she observed that many of her students with language disorders also struggled to learn math and then she made a connection between the two."
