Today it’s not uncommon to find students in a fourth-grade classroom reading books suitable for third-, second-, or even first-graders. Teachers suggest books to students at their deemed “instructional levels,” but how these instructional levels are determined is suspect. With a comprehensive, critical analysis of instructional-level pedagogy, Shanahan exposes its shaky foundations and shows how faulty research findings have become so entrenched. He gathers an extensive body of research studies that overwhelmingly contradict the instructional-level theory and offers an evidence-based consideration of how educators must instead use grade-level reading to bring about maximum learning gains. This seminal book concludes with practical advice for implementing grade-level reading instruction, including detailed descriptions of the types of instruction and scaffolding needed to increase students’ reading achievement, from teaching decoding and challenging texts to scaffolding reading to maintaining motivation. Shanahan asserts that a better approach can ensure that all students have an opportunity to leave high school with reading abilities commensurate with their personal, social, civic, and economic goals.
