Well I actually was paying attention to the presentation and I instinctively hit "no" so that I could see the content again.
Guess who didn't get credit for attending?
A few seconds later, he hears a voice say "......no". So he relaxes with a sigh, and goes to report the all clear to his superior.
That way, not only does it confirm paying attention, but you can also get a signal of course effectiveness.
Or perhaps it's to teach the most valuable CLE of all - too hasty a response risks a critical mistake. I can't even recall the specific topic of the webinar but I definitely learned a lesson!
It was very loud in the quiet classroom, he gave me a look of “now I hate you”, and I didn’t even try to explain that actually, the phone is off.
The LG Nexus wouldn’t ring the alarm when the phone was set to silent.
I literally had to show it to my manager which was furious.
During the final exam of my calculus course, which takes place through two class sessions, my alarm went off to remind me of my second class session. Despite the professor promising to tear up our exams up if our phones made any noise or appearance the hour before, I'm assuming he ignored it because I was literally the only person in class that made any attempt at engaging with his lectures. Unrelated, I had also completely given up studying for the exam since I knew I was going to fail and had plans to retake the course (but be at least present to take mental notes on the final), but he clearly bumped me up to a minimally passing grade for what I can only assume was the same reason.
Edit: it doesn't seem to do that anymore, but it definitely did at least twice, when I didn't have DND on.
Almost like Apple products can have unintended bugs like disabling your alarm on OS update.
Edit: Apologies if the last sentence in my first message seemed rude. Not my intention.
