This two-page summary from Harvard’s READS Lab presents findings from a long-term randomized study of the **Model of Reading Engagement (MORE)** curriculum. MORE integrates science and social studies content with literacy instruction through a spiral design that builds students’ background knowledge and schema over multiple years. The study found that students who participated in three years of MORE outperformed peers in reading comprehension and math, with gains equivalent to more than two months of literacy learning—and these benefits persisted more than a year after the program ended. The research shows how embedding content learning within literacy instruction can strengthen student achievement across subjects.
