I was recently asked by someone at my institution about my open source textbook, Rings
While at the 2020 Joint Mathematics Meetings, I spoke in a Themed Contributed Paper Session on Teaching Abstract Algebra. In my talk, I introduced Rings with Inquiry. If you're interested in my slides, they're available here. I'll be writing more about this project as I prepare the Fall 2020 edition, slated to arrive by July 1, 2020.
