After Claire’s post on accidentally taking a classroom microphone with her after teaching, I grumbled to myself “I wish I taught at a fancy university with a fancy microphone in the fancy classroom.” One email later, I learn that there is a microphone in the computer cabinet in the classroom where I teach 130 students. I tried it out today, hoping to counter a sore throat after flying back from FOCS*. Apparently it worked really well, the students in the back were answering more questions and one student after class asked me to use it in future classes.
Sadly, it means that maintaining my sanity with comments murmured under my breath is no longer possible.
* I will post on FOCS when the talks from the conference are available so I can point to my favorite talks.
