As the new coronavirus swept across the Seattle area, one of the hardest-hit areas in the United States, the University of Washington earlier this month shuttered its classrooms in a bid to contain the spread of the disease.

But lecturer Ian Schnee's philosophy class for 300 students took place as scheduled on March 9 — just online. Eighty tuned in live, with more expected to watch the recording later.

Schnee's other teaching also happened virtually, with 20 students joining a video-streaming chat room to share answers to logic problems and ask questions before upcoming exams.
