The document discusses the results of Project Follow Through, the largest educational experiment ever conducted by the US government. It found that the Direct Instruction model produced significantly better results in basic skills, cognitive skills, and affective skills compared to other models. However, the findings were not widely adopted due to resistance from those committed to alternative philosophies and the significant changes required in teacher training. Additional research continues to support explicit, systematic phonics instruction in learning to read, yet many public schools do not implement these evidence-based practices.
