I cannot remember attending any conference where no phone rang – be it a call or a message alert. I blame not the device but the owners. How hard is it to remember to put one’s phone in silent mode when attending a conference?
More so, how difficult can it be to lower your voice when an expert is speaking in front? Should you have any concerns, why not raise your hand and share your thoughts to the audience – not just your seat mate.
And how, can we teach our students to bear in mind these ethics when professors themselves (not from where I came from) fail to observe them?
