All students are different. They show up on the first day of school with different strengths and weaknesses as well as varied levels of readiness and motivation. For teachers to continue to believe they can address all these differences with one lesson for the whole class for the majority of the school day is folly. This practice is simply unfair to our students and must change if our schools are ever to realize legitimate education reform. This book attempts to address the parameters surrounding this issue while also offering strategies as to how this can be accomplished, PreK-16. Teachers should not be hesitant to attempt the model described herein because of its seeming complexity. It's not as difficult as it may appear and can be implemented incrementally into your school day. Once established, it's no more work than a traditional classroom. Some parents will be thrilled to know their child will never have to wait for the rest of the class to catch up to their pace of learning. Other parents will be equally pleased to realize their child will not have to struggle in an attempt to keep up with the rest of the class; that if their child needs more time to learn a lesson or concept, they'll have it. In short, it's a win/win for all students. As the orchestrator of this environment, teachers will feel a much greater sense of accomplishment at the end of the day. They will conclude they have successfully met the needs of all their students regardless of how fast or slow each one moves through the curriculum.
