The collection begins with Maya Eagleton’s overview of the two main categories of student disabilities—low-incidence and high-incidence. While students with low-incidence disabilities tend to have a higher level of impairment, children with high-incidence disabilities are harder to assess and therefore may not receive the appropriate interventions. Eagleton also discusses two models of disability assessment that help to identify students who require special education services. Cynthia Vejar covers a number of mental illnesses that can affect a student’s academic performance, including oppositional defiant disorder, conduct disorder, anxiety, depression, Autism, and Asperger Syndrome. Vejar describes the symptoms of each and offers teaching techniques and strategies that can help accommodate these students’ particular needs. The following article describes the impact of the Individuals with Disabilities Education Act and the different points of view on the benefits of mainstreaming students with physical disabilities.
