I spent a little time searching through the Wikipedia recently. The Wikipedia is an encyclopedia available for free and that anyone can edit. Because anyone can edit an entry, it is self-correcting. I was surfing the Wikipedia to see how things related to special education had changed there since my last visit.
There is no entry for “emotional or behavioral disorders” nor variations on that set of terms. Neither is there an entry for “serious emotional disturbance” (the U.S. term), but there is an entry for “emotional disturbance.” Here’s that entry, in its entirerty:
An Emotional Disturbance is a catagory of Special Education in the United States of America. It is defined by it’s impact on the child’s ability to function successfully in a mainstream (or regular) classroom.
Looks like it needs some editing. I’ll have to dig up the time.
