This document discusses differentiated instruction, which is an approach to teaching that recognizes students learn in different ways and at different paces. It defines differentiated instruction as proactively planning varied approaches to content, learning processes, and products based on student needs. The document provides examples of differentiation strategies like modifying content based on student interests and readiness levels, using flexible grouping, and assessing student growth over time rather than comparing students. It emphasizes differentiation is a philosophy, not just a set of techniques, and should be implemented along a continuum from minimal to extensive based on student needs.
