Are we missing the opportunity to reach struggling learners from the very beginning? Are we hastily--and unnecessarily--referring students to intervention programs that substitute for high-quality core instruction? What if we could eliminate the need for intervention programs in the first place? Response to Intervention (RTI) programs are only as powerful and effective as the core instruction on which they re built. High-quality instruction, then, is the key ingredient that helps all students excel, and it s at the heart of Douglas Fisher and Nancy Frey s unique approach to the RTI model--Response to Instruction and Intervention, or RTI2.
