Differentiated instruction is an approach to teaching that involves actively planning and modifying instruction based on students' needs, interests, and readiness levels. The document outlines steps to differentiate instruction, including getting to know students as individuals and learners through assessments and learner profiles. Key aspects of differentiation include ongoing formative assessment, recognizing diverse learners, flexible grouping, choice, and scaffolding instruction. Differentiation can be done through content, process, product, and learning environment based on factors like readiness, learning style, interests, and thinking style. The goal is to improve student learning by presenting material at appropriate levels and showing students that their teacher cares about them.
