I'll start!
1) My high school European history teacher. She lectured nearly everyday for nearly the whole class, but she was super passionate about her subject matter, funny, and not afraid to tell us the scandalous details of various European figures' personal lives (e.g. the sex lives of European monarchs, who had the consistent habit of marrying their cousins!). She also challenged us to become better listeners, note takers, writers, critical thinkers, and to think like a historian.
2) In my Lessons of Vietnam class we had to make videos on various topics, like illegal immigration and the Vietnam War itself. My friends and I made some videos that were probably not appropriate for class (e.g. simulating jungle warfare by pretending to ambush one of my friends with a huge bowie knife and using ketchup as fake blood!), but we had a great time doing it and learned a bit about making videos and recent U.S. history in the process.
Part 2 was much harder to answer than part 1! Definitely harder to remember the content than the people.
