I taught a university course this last semester. In person. Up to 100 students in the lecture theatre. I managed to avoid catching #COVID19, or any kind of virus, actually. Here's the scoop: /1
#CleanAir: The lecture theatre was in a very old building, luckily it had windows. But they were up REALLY high, so I took my own ladder and climbed up and opened all of the windows. I also propped open the doors at the front and back. I warned the students to bring a jacket /2
This dropped the CO2 from around 2000ppm to around 700ppm in ~ 10 mins. I also ran an air purifier at the lectern, on full. I kept my mask on until the CO2 dropped below 800ppm. /3
I masked at the end of the class so students could come and talk to me. Most of them masked when they did this, without me asking. At one point I had almost 20% of the class testing positive for #COVID19. /5
The feedback from the course was overwhelmingly positive. I had no complaints from these young people about any of these measures. I also hope that I reduced at least some spread by introducing ventilation into a poorly ventilated lecture theatre. Overall, good success. /fin
@AndrewDickson13 My experience was largely the same. Students are happy to practice C0VID safety when presented with scientific evidence. I'm the local faculty member most students confide in when they need help on C0VID issues. x.com/michael_hoerge…
