There is no magic in the word "differentiation." What always counts in the classroom is the quality of practice, and quality differentiation is both complex and promising. Through the use of lessons at a variety of grades and in a variety of subjects, this session will help educators explore what is involved in planning high-quality differentiation that benefits a wide range of learners. Participants will look at positive and negative examples of differentiation, and analyze how teachers can modify instruction to benefit a range of learners while maintaining responsibility for content standards.
