In early February, I was working from home when I received a message informing me-and all the other professors at my university in China-that courses would be taught online because of the novel coronavirus. I was already feeling anxious about the mounting epidemic, and my university had locked its doors a few days earlier. Then, when I realized I'd have to teach students online, my anxiety level grew. I didn't have any experience with online teaching platforms. I was also skeptical about how effective they'd be. "How will I gauge the students' reactions to my lectures through a computer screen?" I wondered. "Will they learn anything?"
