Access to opportunities must be created for all students - but what do you do when a student has a behavioral disability? I once had a student who could not sit still and would speak up every 5 mins and had a nervous tic. and jerky movements.
The modification I made was to teach him the acronym WAIT - Why Am I Talking? and ask him to write his questions or comments down, and we would spend 5 mins after class going over what was written rather than have him talking (or yelling) out every five mins.
