 Hypothesis for me was the most common tool that I recommended to people. First of all, I think at that point we already had integration with hypothesis in our LMS, which is Canvas. As we were trying to figure out what programs, what kind of tools in our digital tool kits to throw at a bunch of faculty members who had never taught online, hypothesis made the most sense because it's something that you can use across the curriculum, whether it's a person who is reading scientific studies, they're able to quickly pop in some annotations or creating a primary source historical kind of engagement, historical document engagement activity. It just, like I said, it just made sense.
