Synthesizing cutting-edge research from multiple disciplines, this book explores how young children acquire knowledge in the real world and describes practical applications for early childhood classrooms. The breadth and depth of a child's knowledge base are important predictors of later literacy development and academic achievement. Leading scholars describe the processes by which preschoolers and primary-grade students acquire knowledge through firsthand experiences, play, interactions with parents and teachers, storybooks, and a range of media. Chapters on exemplary instructional strategies vividly show what teachers can do to build children's content knowledge while also promoting core literacy skills.
