"There is no nobler act than teaching someone to read." -Tim Shanahan
Decoding was essential, but insufficient for success. That’s why Reid Lyon, Jack Fletcher, Barbara Foorman, Joe Torgesen, and so many others endorsed more comprehensive approaches to meeting children’s reading needs (Fletcher & Lyon, 1998).
They were quite explicit that the teaching of these components takes places simultaneously, not consecutively or sequentially. It would be cruel to put all the emphasis on one part of the process, while allowing kids to languish with the other parts (sort of like providing calcium by taking away the protein).
