I would like to echo the comments of others on this thread and acknowledge what a wonderful time I had listening to Professor Yamashita. He has a delightful sense of humor and an incredibly engaging method of instruction.
I am especially grateful of his way of using "puzzles" to guide discussions. Since the session, I have incorporated that strategy in my classroom. I have students exclaiming, "I think I've figured it out!" Whether they are right on or way off, it makes students think and they enjoy it because they see it as a game. I'm sure that I have a long way to go before perfecting the strategy, but I do enjoy refining it. This goes to show that one of the many benefits of this seminar includes learning new and improving old teaching strategies. It's not just about the content (and there is A LOT of content)!
