How can children with intellectual disabilities cope with the curriculum of elementary school? How should I, as a teacher in an inclusive setting, teach when I have not studied special education? This book provides solid background knowledge on the specifics of teaching children with and without intellectual disabilities together: fundamentals, didactic core elements, educational goals and content, as well as key principles and methods of instruction. It also highlights conditions for success and potential pitfalls to ensure that inclusive teaching can be effective.
