This book addresses issues related to school inclusion from the perspective of systemic inclusion. It focuses on the need to face the challenges of inclusion in education from a broad perspective, including the classroom, the school as an institution, families, and the community. It also pays attention to the full interactions between them. The book demonstrates how inclusion can be carried out in very real, concrete and everyday ways. It also shows how researchers can work hand in hand with the professionals and other stakeholders who are developing their practices day by day. The book draws on a range of research projects of the Spanish and international research groups to provide both rich theoretical frameworks and rigorous research outcomes related to the four dimensions of the systemic inclusion perspective and its necessary networking: classroom, school, families and the community. Most of the chapters take Spain as the case study but, far from being a local book, it uses Spanish analysis to dialogue universally with current main debates and challenges in inclusion, almost 30 years after the Salamanca Statement.
