Grounded in the best current knowledge, this book shows how to implement Response to Intervention (RTI) in middle and high school contexts. Detailed guidelines are presented for teaching reading comprehension, vocabulary, and other aspects of literacy across the content areas, and for providing effective interventions for students who require additional support. The authors describe RTI procedures that are specifically tailored to the needs of struggling adolescent learners and that take into account the challenges and logistics of secondary-level implementation. More than 20 reproducible tools for planning, assessment, progress monitoring, and multi-tiered instruction are featured; the large-size format facilitates photocopying.
