This document discusses Universal Design for Learning (UDL) and differentiation. UDL is a method of lesson planning that ensures all students have an equal opportunity to learn by providing multiple means of representation, expression, and engagement. Differentiation is adjusting teaching methods to meet student needs throughout the lesson. Both aim to meet diverse student needs and provide access to the curriculum. The document explores how UDL requires advance planning while differentiation focuses on adjusting during instruction. It proposes using both UDL and differentiation to anticipate and address varying student needs.
