Researchers have found that preschoolers whose teachers who make small references to print while reading aloud to children (pointing out letters or words, running finger under words from left to right, etc.) show increased reading skills later when compared to children whose teachers do not. This is a small change for teachers that pays in huge dividends. We can (and do) do this in storytime as well! Read more about the study in this article from Science Daily.
Thanks, Melissa, for pointing out the article!
