Have you ever learned something really cool, and then had trouble explaining it to someone? Have you ever taken a class and just not understood it no matter how hard you tried? I'm a graduate student who has taught Splash classes for over six years (some of which I've even heard were pretty good!), and I've experienced good and bad classes as both a teacher and a student. I've taught students about analytical biochemistry by making a class about international espionage, improvised a lesson about the history of Boston as a substitute teacher for a class about Ronald Reagan, and once wound up having a Splash class go far better than normal when I had none of the equipment I had planned to use. In this class, we're going to discuss what I think made these classes good and what made other lesson plans go bad. I also would love to hear about any experiences you all might have had. Then, we'll see how we can use what we've learned to make better presentations, explain your ideas to anyone, and maybe even change the world. This will be a discussion-based class, although I'll be showing some examples from past classes to get the conversation started.
