And yet, her book has sold millions of copies (self-published of course; no peer review process like the rest of us have to go through to ensure trustworthy research and assertions), and districts spend tens of thousands of dollars for RP herself and affiliates to come speak to teachers.
There are many alternatives, folks. Much fabulous research on poverty and social class that researchers agree with and recommend to teachers and principals all the time. They’re not quick-fixes (like RP offers) because social inequities were not created overnight, but there are many instructional and interrelational approaches that have been proven to be in the best interest of children and families from low income homes.
