"Interactive Shared Book Reading" is a general practice that adults may use when reading with children and is intended to enhance young children's language and literacy skills. Typically, "Interactive Shared Book Reading" involves an adult reading a book to a child or a small group of children and using a variety of techniques to engage the children in the text. Two related practices are addressed in the What Works Clearinghouse (WWC) intervention reports on "Dialogic Reading" and "Shared Book Reading." Two studies of "Interactive Shared Book Reading" met the WWC evidence standards and one study met the WWC evidence standards with reservations. Together these three studies included over 100 preschool children from the Midwest and Florida, and they examined intervention effects on children's oral language, print knowledge, and early reading/writing. The majority of the children were from economically disadvantaged families and many were considered at-risk. This report focuses on immediate posttest findings to determine the effectiveness of the practice. "Interactive Shared Book Reading" was found to have mixed effects on oral language, no discernible effects on print knowledge, and potentially positive effects on early reading/writing.
