Differentiated instruction is a teaching philosophy that aims to modify instruction to meet the varying needs of students. It involves creating multiple paths so that students of different abilities can learn in ways that are appropriate for them. Teachers can differentiate instruction through content, process, and product based on students' readiness levels, interests, and learning profiles. Some strategies for differentiated instruction include learning modalities, multiple intelligences, learning contracts, tiered activities, and RAFT. The goal of differentiated instruction is to maximize each student's growth by recognizing that students learn in multiple ways and respond uniquely to different teaching approaches.
