Differentiated instruction is an approach to teaching that involves modifying instruction based on student needs, interests, and abilities. The teacher proactively plans lessons using varied content, processes, and products to engage students with different backgrounds, knowledge levels, and learning preferences. Ongoing assessments, both formal and informal, are used to understand students and guide instructional planning rather than just assigning grades. Differentiating instruction leads to fewer discipline issues, significant student growth, and more positive teacher-student interactions.
