I do play games as learning tools but usually for review. I like the idea of using them to introduce content. Most if not all of the group activities will work well no matter what the class is.
My trouble is usually having the time to prepare for the activity ahead of time,as I do not have a lot of prep time, and figuring out how to work it into the class. I generally try to have at least one student centered activity for each class period (usually 2 hrs) but still have struggled to cover content.
I think I still end up lecturing much of the time because it does not take as much prep time and Icahn cover the most content that way.
I am still trying to figure out how to worry less about providing the content for the students, after all they do have a textbook, and concentrate on creating meaningful ways of helping them move the content into memory.
