I call Diane Snowball the reading guru.  With more than fifty years experience under her belt, which includes a lengthy consulting stint in New York, her knowledge about how children learn to read is outstanding. In this second episode, Di talks about the importance of building world knowledge, scaffolding learning and the philosophy behind flexible small group teaching. Di urges teachers to steer clear of reading programs; it's understanding how learning takes place and what it looks like in reading that makes all the difference.
