I've been teaching a course called "Origami in Math and Education" for my university's Masters program for in-service math teachers (middle- and high-school) for many years now. Just recently I taught this course online, advertising it on social media in case anyone else wanted to take it. To my surprise, several people from the origami and math communities signed up for the course. As a result, the students in the class ranged from people with Ph.D.s in math to high-school math teachers to math-interested artists. The interactions between these groups gave the course a dynamic and intensity that I had not encountered before. In this presentation and discussion, I will relate some stories from this class, the new things I learned from it, and some of the excellent teaching projects that emerged from the students' work.
