I don't like intellectual disability any more than I do mental retardation. This term went out decades ago in the world of modern medicine to mentally disabled. I don't like labels much at all. Any label will still scream to a child "you are different than everyone else".
In schools, in particular, I would like to see ALL such descriptions changed to read "learning difference". We need to strike negative words like disability and challenged. Most kids are not disabled, per se. They merely learn differently than is being taught and that in itself is the challenge.
When schools teach by doing, seeing and hearing, rather than memorization only then will all normally intelligent children be equal. Children with actual medical illness that prevent learning, such as, microcephaly or severe down's syndrome of course will be exempt and need to be clearly classified are challenged due to the severity of their disease. However, children with ADHD, Asperger's, Tourette's, etc., who are merely hands on, visual or auditory learners are not truly challenged by learning. They are quite intelligent. It is the teaching method that fails to spark their ability to retain the knowledge.
Legislators, please, for kids sake get rid of ALL negative words PERIOD! Do not lump many conditions under one inadequate phrase. And pass legislation that prevents districts from putting in classes that teach substandard material. Washington needs to rise above the bottom of the American barrel in education. This is how it can be done.
