Differentiated instruction is an approach to teaching that involves adjusting the curriculum, teaching strategies, and classroom environment to meet the individual needs of students. It is based on ongoing assessment of student needs and abilities. Teachers using differentiated instruction employ flexible grouping, tiered lessons, learning centers, and other strategies to accommodate different learning styles, interests, and levels of readiness among students. The goal is for all students to achieve academic success through clear expectations and an emphasis on individual strengths.
