Tried out experiment in my micro class and did an excellent lecture in the other. The class with the experiment did better on the supply and demand exam.
I could not figure out why did better so I asked my class on Friday. They told me that they were motivated to read because of the exam. Few of them reported that they were confused when we did the experiment, and they made the connection as they read to the confusion in class.
So it appears that experiments alone are not enough. There is a need for some old fashion reading too.
I used Charles Holt design, so he gets a link on my tiny blog.
