Two-thirds of U.S. high school students today are unable to read and comprehend complex academic materials, think critically about texts, synthesize information from multiple sources, or effectively communicate what they have learned. And in response, many teachers simply stop assigning challenging texts, opting instead to "deliver content" through lectures. For 25 years, though, the Reading Apprenticeship program has shown that when school and district leaders embrace a collective responsibility to provide effective reading and writing instruction, they can help subject-area teachers reflect on their own literacy practices and fundamentally rethink their approach to literacy instruction.
