It sounds like it all comes down to courtesy, respect for others, and common sense. It is rude to interrupt someone's conversation with an unrelated question no matter what language is used. That is something small children do and are quickly corrected by their elders. I've never been to a deaf event. Is it possible to have suggestions posted at the event on proper manners for ASL students without offending everyone or issue voluntary tags to identify a student? That way anyone willing to help them will know who they are and they won't be as likely to bother others. If it is voluntary it wouldn't seem they are being picked on but helped.
That teacher should include social skills as part of the class grading system and then give lower grades to the students who ignore deaf people in the class when they talk among themselves. Other assignments are after class time (homework, etc.) so it would be reasonable for it to be counted in the grades.
