SUNY has been pushing for more online for some time. It means an increased ability to sell credentials to a broader market with lower real estate costs.
As far as I can tell, the primary constraint has red tape. I don’t know who put it there (unions? accreditors? governments?), but getting a class certified to go online on my campus has meant going through a steep enough up front cost that few people bother. Combine that with the fact that an online class is simply less fun and you’ve got a recipe for a mercifully slow expansion of online teaching.
That changed this week. Now almost all of SUNY is online, like it or not. The red tape might be there when we get back to normal, but the up front cost to getting a class online will fall enough that many adjuncts will get in on the action next fall.
About 15% of summer 2020 classes are slated to be led by adjuncts. I predict that by summer 2021 that will increase to 25% and that will just be the start of a much larger trend of adjunctification of online classes.
