In seeing the sections about synchronous chat and asynchronous chat, I'm struck by how video conferencing - especially in these days of COVID19 - is taken for granted as if it's always been a part of online learning. It's interesting how the content in this course, so far, speaks to when online learning was more about trying as best as possible to offer a nearly as good simulation of brick and mortar learning vs. how today, it can achieve outcomes far beyond the limits of in person, conventional classes.
