Excellent text book layout/format - well organized, easy on the eyes and mind: chapter outlines,consistent style throughout, ample engaging examples, simple explanations, cross-reference materials, diagrams, and data forms. A good intro to ABA - as a teaching method, not just a way to control students, applicable in general education classrooms, special education and at home. The authors clearly delineate research based facts from assumptions (I.e. teachers use several of these methods in combination and see results x, "but it is often impossible to identify which components...are actually influencing behavior" p. 351).
