Differentiated instruction is an approach to teaching that aims to maximize student growth and success by tailoring instruction to meet individual student needs. It recognizes that students have different backgrounds, readiness levels, interests and preferences for learning. Teachers differentiate content, process, product and the learning environment based on formative assessment of student needs. The goal is to challenge and support all students by matching instruction to where they are in order to help them learn effectively. Differentiation is not a single strategy but a philosophy of teaching through flexible use of multiple materials and strategies.
