Differentiated instruction provides varied approaches to content, understanding ideas, and effective learning. It is not individualized instruction from the 1970s or chaotic, but is proactive, qualitative, student-centered, and uses assessment to provide a blend of whole-class, group and individual instruction. Key strategies include clear rules and assessments to guide planning, engaging lessons emphasizing critical thinking, and creating a safe classroom where students are challenged at an appropriate level through scaffolding, choice, and thinking strategies like jigsaw, think-pair-share and cubing. The goal is to encourage students to work beyond their comfort zones.
