Much of education theory is rooted in misconceptions and ideas not rooted in evidence, says Australian researcher and instructional coach Nathaniel Swain, author of Harnessing the Science of Learning. Learning styles, “guide on the side” teaching, teaching “21st Century skills”—these ideas show up in classrooms every day, even with no evidence they are effective ways to increase student learning.

But evidence does exist on how students learn and what teaching methods can be more effective. In today’s letter, I interviewed Swain about the misconceptions, and the evidence-based ideas that can replace them.

These aren’t the only pieces of evidence that matter to teaching and learning, of course—but they provide an overview on the big ways teaching might change. Here are Swain’s 4 big ideas from the book to help teachers and school leaders reorient classrooms away from myths and misconceptions, and move toward evidence of effective learning.
