It has been recognized since the 1980s that literacy begins to develop a long time before formal schooling begins. In today's literate environment, children start learning to read much as they learn to speak, through playful print interactions with their parents, older siblings, or other adults, beginning in year one. A sharp debate about the best approach to developing early childhood literacy is now brewing between reading instruction experts, who tend to advocate direct instruction of skills, and preschool educators, who know that preschoolers learn best through play. This book provides a model for action that may help to settle the debate.
