[Solution] Written Numerous Books
Consider this statement: When a teacher tries to teach something to the entire class at the same time, chances are, one-third of the kids already know it; one-third will get it; and the remaining third won’t. So two-thirds of the children are wasting their time. —Lillian Katz, EdD
Lillian Katz is a well-known leader in the field of early-childhood education. She lectures all over the world and has written numerous books and articles on elementary education, teacher education, and parenting. Like Tomlinson, Katz advocates for instruction that is differentiated to meet the needs of all learners.
