In today's diverse educational landscape, meeting the needs of all students remains a critical challenge. Differentiated instruction (DI) has emerged as a pedagogical approach aimed at addressing this challenge by tailoring teaching methods and content to accommodate varying learning styles, abilities, and interests within a single classroom. This research article explores the principles, strategies, benefits, and challenges associated with differentiated instruction. By examining current literature and empirical studies, this paper aims to provide educators with a comprehensive understanding of how DI can be effectively implemented to enhance student engagement, academic achievement, and overall learning outcomes.
