Keynesian vs. Hayekian Economics

A couple of weeks ago, my Grade 10 students were to begin their exposure to the workings of Economic Globalization.  They are expected to have a basic understanding of the different economic philosophies behind capitalism; specifically the ideas of John Maynard Keynes and Frederick Hayek.  These are fairly esoteric ideas for a Grade 10 student to fully comprehend, so I decided to take an alternative bent.

First I showed them the following cartoon:

Since I was relatively confident that few if any of the students would get the joke, it seemed the perfect hook to encourage engagement.  I told the students that it's alright that they didn't understand this now, but by the end of class, everyone would be in on the joke.
One enterprising young man suggested that the cartoon had something to do with the man's wife being from Kenya. 
Regardless, as we combed through the intricacies of Supply-side (Hayek) vs. Demand-side (Keynes) economics, mainly in note-taking form, it was clear that only about a third of the class understood the joke. This was easily assessed as the various students reactions upon understanding the original cartoon were boisterous and audible.

To reach those students who still weren't in on the joke, we used a couple of YouTube creations from Econ Stories to flesh out the ideas behind these thinkers.

The first video recounts the debate between these ideologies:

 

And the sequel applies the philosophy to current economic situations.:

 

By the end of the second video, each students has a list of characteristics of each view on capitalism.  More interesting to me as a teacher, is that I had a constant flow of information coming from the students regarding their understanding.  Without any type of summative assessment, I can be reasonably sure that each student has an understanding based on their in class reactions.

This is a lesson strategy that I would like to repeat.
