Dissertations

SIZE DOESN’T FIT ALL: IMPLEMENTATION OF DIFFERENTIATED INSTRUCTION-A CHANGE LEADERSHIP PLAN

Differentiated instruction is an approach to teaching in which educators actively plan for students' differences so that all students’ academic needs are met. It is also a process of ensuring that what a student learns, how he or she learns it, and how the student demonstrates what he or she has learned is a match for that student's readiness level, interests, and preferred mode of learning (Tomlinson, 2008). In a differentiated classroom, teachers divide their time, resources, and efforts to effectively teach students who have various backgrounds, readiness and …
