“A professor at Columbia University is calling on her fellow professors to give their students an “automatic A” for the spring 2020 semester due to the Wuhan coronavirus. According to professor Jenny Davidson, “it’s time to abandon our preconceived ideas about what needs to happen in a college class for a student to get credit for it.” Columbia University professor Jenny Davidson is calling on those who work in academia to give their students A’s for the spring semester, because of the coronavirus. The professor made her case in an op-ed for the Washington Post, entitled, “Forget distance learning. Just give every college student an automatic A.” “At the very least, the coronavirus means universities should switch to pass-fail and pass everyone,” wrote Davidson, adding that “it’s time to abandon our preconceived ideas about what needs to happen in a college class for a student to get credit for it.” Davidson went on to claim that professors and students are just too “stressed,” adding that she hopes faculty and staff “won’t break under the huge additional workload entailed in moving courses online.” “We’re now scrambling to transition everyone to remote learning on short notice,” said Davidson.
