The authors of this introductory text have a vision for special education—to equip general and special education teachers with the principles, values and teaching practices that support the education of the majority of students with disabilities in general education programs. Beginning with a thorough review of the principles that undergird IDEA and the process of nondiscriminatory evaluation, the authors explore the teaching and collaborative processes necessary for implementing best practices and Individuals with Disabilities Education Act of 1997. Using a categorical approach, the authors highlight real students with real disabilities and use their stories as a vehicle for describing the characteristics, causes, and challenges that people with exceptionalities face and that both general and special education teachers must consider when making decisions about how, where, and what to teach.
