premise: As older preschoolers begin to attend to features of print, adults can combine shared book reading with scaolding of children's knowledge of letter names, letter-sound correspondences, and print conventions (for example, that books are read from left to right and top to bottom of the page, that spaces are used to separate words and periods to end sentences).
hypothesis: When preschoolers start reading, their parents can share their basic reading skills and knowledge with their kids.
