Knowing whether or noto knowing how to pitch things at what level is a huge one. You have to decide what and how you teach and at what level. And i don't think a lot of faculty give themselves credit for that. I've watched people who were poor teachers, or people who are not teachers who tried to teach. It runs tise injustas i don't get no, it wasn't pitched the right way at the right level. Just hugely important. When i think about the many challenges that have been exasperated by the pandemic, one of them is most definitely cognitive load.
