Differentiated instruction adapts learning to the students' unique differences. It focuses on the diverse needs of the individual learners. It is stated, that the first step in developing a differentiated instructional program is to provide an introduction to the philosophy and an overview of the benefits for learners. After the introductory phase, teachers need to identify existing practices that effectively differentiate instruction. Lastly, teachers engage in reflection and discussion. The author presents and discusses 11 practical ways to guide teachers toward differentiation. These are: (1) know the standards; (2) vary instructional strategies and activities; (3) create learning climate; (4) exhibit "withitness"; (5) provide a wide variety of materials and resources; (6) know the students; (7) assess before, during, and after the learning; (8) adjust assignments; (9) plan students-focused opportunities; (10) use flexible grouping designs; and (11) know change is gradual.
