Valentin Guerra has cracked one of the hardest problems in education, how do you give every student personalized writing feedback when you have thirty kids in a class and one of you? His answer is a custom AI writing tutor built inside MagicSchool that uses state rubrics and the RACER writing strategy to give students immediate, actionable feedback without ever doing the work for them. In this course, Valentin walks you through exactly how he built it and hands you the actual prompts so you can implement it in your classroom the same day. This isn't about using AI. It's about integrating it in a way that makes your students genuinely better writers.
