The Scientific Principles of Reading Instruction provides a summary of the current scientific consensus on reading and writing instruction, as can be found through the interpretation of meta-analysis. The book summarizes the findings of dozens of meta-analyses in order to establish what we do and don't know about teaching students how to read and write. The book covers the topics of phonemic awareness, phonics, morphology, vocabulary, "sight words", fluency, comprehension, spelling, writing, programming, sound walls, and intervention.
