We do have disability and SEN lists and we do make reasonable adjustments of course for many. We do not have (maybe just yet) selective muteness listed as a disability, or someone requiring a particular adjustment in class not to be called out on that basis - it might happen of course, I am not familiar with disability rules on whether this would warrant an adjustment. Such grey areas are decided upon by a committee, which is usually favourable to students. So yes, there might be case for reasonable adjustment, with the operative word being “reasonable” .
What would reasonable mean in this context? In the class there would be not be a requirement for me to memorise 200 names lol. (In those cases we do the soft toy throwing game. In Harvard style students can also have name tags on them.)
Neither there would be a requirement to change my style of teaching. It is a well established method where entire classes are taught in this way. In fact faculty who can teach this way is sought after, with teaching demonstrations being a part of interviews. I dont see it going away at all I’m afraid.
Maybe the student would be encouraged to take another course, or not attend and watch it online. Some classes wont be able to be recorded, due to their nature and content. I would prefer the student not took this class, because participation is more effective than watching the lecture like a TV series. So they would be automatically at a disadvantage.
Anyway, no need to be a snarky saying I should remember all students otherwise “I should ask for an adjustment"; clearly not possible in every case. Usually, normal, mature people, teacher or student, meet in the middle and there is no escalation.
