Making my first appearance on Substack Notes to alert readers to my new post on a truly groundbreaking development.

The first long-term study of an elementary curriculum that systematically builds knowledge (believe it or not, most elementary curricula don’t) has found eye-popping gains on standardized reading tests.

Hope this helps convince those who say there’s no proven connection between knowledge-building and reading comprehension—and reassures the many schools starting to adopt this approach that they’re on the right track.
