Crimmins (Westchester Institute for Human Development; New York Medical College School of Public Health) offers a manual for K-12 teachers dealing with students who have persistent or severe behavioral problems. He introduces educators to the positive strategies method, designed to help teachers understand why behaviors persist, prevent problem behavior, and replace challenging behaviors with better alternatives. He explains how to conduct functional behavioral assessments, how to develop behavior intervention plans, and how to assemble effective school teams. The method is grounded in the schoolwide positive behavior support (PBS) approach, and can be used for students with or without special needs.
