Since the 1970s support for people with disabilities has grown significantly, as reflected in the United States by three key pieces of legislation: the Rehabilitation Act of 1973, Americans with Disabilities Act of 1990, and the Individuals with Disabilities Education Act (IDEA). The support has led to new educational practices, including alternative assessments for students with disabilities, placement in the least restrictive environment, and individual educational plans.
There are many ways of classifying people with disabilities, all of which carry risks of stereotyping and oversimplifying individuals' strengths and needs. For the purposes of education, the most frequent category is learning disabilities, which are difficulties with specific aspects of academic work. The high prevalence of learning disabilities makes this category especially ambiguous as a description of particular students. Assistance for students with learning disabilities can be framed in terms of behaviorist reinforcement, metacognitive strategies, or constructivist mentoring.
Attention deficit hyperactivity disorder (ADHD) is a problem in sustaining attention and controlling impulses. It can often be controlled with medications, but usually it is also important for teachers to provide a structured environment for the student as well.
Intellectual disabilities (or mental retardation) are general limitations in cognitive functioning as well as in the tasks of daily living. Contemporary experts tend to classify individuals with these disabilities according to the amount and frequency of support they need from others. Teachers can assist these students by giving more time and practice than usual, by including adaptive and functional skills in what they teach, and by making sure that the student is included in the daily life of the classroom.
Behavioral disorders are conditions in which students chronically perform highly inappropriate behaviors. Students with these problems present challenges for classroom management, which teachers can meet by identifying circumstances that trigger inappropriate behaviors, by teaching interpersonal skills explicitly, and by making sure that punishments or disciplinary actions are fair and have been previously agreed upon.
Physical and sensory disabilities are significant limitations in health, hearing, or vision. The signs both of hearing loss and of vision loss can be subtle, but can sometimes be observed over a period of time. Teaching students with either a hearing loss or a vision loss primarily involves making use of the students' residual sensory abilities and insuring that the student is included in and supported by the class as well as possible.
