For children stuck on a difficult word, Professor Calkins said little about sounding-out and recommended a word-guessing method, sometimes called three-cueing. This practice is one of the most controversial legacies of balanced literacy. It directs children’s attention away from the only reliable source of information for reading a word: letters.

For decades, Lucy Calkins has determined how millions of children learn to read. An education professor, she has been a pre-eminent leader of “balanced literacy,” a loosely defined teaching philosophy.

Whole language was a movement of people who believed that children and teachers needed to be freed from the tedium of phonics instruction. Phonics lessons were seen as rote, old-fashioned, and kind of conservative. The essential idea in whole language was that children construct their own knowledge and meaning from experience. Teaching them phonics wasn't necessary because learning to read was a natural process that would occur if they were immersed in a print-rich environment. Whole language proponents thought phonics lessons might actually be bad for kids, might inhibit children from developing a love of reading by making them focus on tedious skills like breaking words into parts.

We are born wired to talk. Kids learn to talk by being talked to, by being surrounded with spoken language. That's all it takes. No one has to teach them to talk.But, as numerous studies have shown, reading is different. Our brains don't know how to do it. That's because human beings didn't invent written language until relatively recently in human history, just a few thousand years ago. To be able to read, structures in our brain that were designed for things such as object recognition have to get rewired a bit.
