Reading is Fundamental did something amazing. They wanted to reduce summer slide (summer learning loss) from 80% of kids to 40% of kids, mainly poor kids without access to books. Well, they did that. Consistently, over two years of a study in which they let kids choose and keep books within their reading lexile, and gave teachers support around how to teach those texts in school. Summer learning loss dropped to 37%. But what they did not expect was this: they INCREASED learning (as per Iowa Test of Basic Skills) in 57% of children. The greatest gains were seen in kids in the bottom 10%, kids deemed to have learning problems.
This is huge. HUGE. No, it's not sexy. It's not going to break the internet, but if you understand the cumulative cost of summer learning loss to poor kids, it's a damn miracle.
I love RIF.
