Publisher description: Differentiated instruction (DI) is a powerful way to meet the individual and diverse needs of all learners, including the adult learner engaged in job-embedded professional development, staff training, and faculty meetings. Best-selling author Gayle H. Gregory uses a "one size doesn't fit all" approach to faculty training, observation, and supervision for DI implementation, enabling teachers, trainers, and principals to identify their own unique strengths and concerns as they work to engage students in the classroom.
