I am a Masters Student in a public University in New York state. I do not consider myself to be disabled in any form but I do find it difficult to concentrate in class. I lose focus too often and have difficulty recalling concepts taught during class. So I find resources such as recorded lectures to be very quite beneficial as whenever I lose focus while watching them, I can simply rewind back.
I am currently enrolled in a course where lectures are not recorded. I like this subject and I want to do well. So I want to ask the Professor permission to audio-record his lecture (by just keeping my phone on my desk and not using any distracting piece of equipment). I don't know the professor well but he definitely isn't one of those overtly friendly ones who (you'd think) will surely give you permission.
What I want to know is if he were to deny me, what could be his reasons?
I think I have just one shot at this. So I want to go there prepared.
A vaguely similar (but not same) question has been asked before.
