Using whiteboards to teach externalities graphs

I held my annual whiteboard competition with my A2 Economics class to see who could draw the best 4 graphs showing Positive and Negative Externalities of Consumption and Production. The winner this year was Fiona Leng with two highly recommended by Jemima Hodgson and Yanz Chen.

The externalities topic at A2 Level Economics involves being able to draw and understand four graphs. A different way of teaching this area of the course was to get students to use A3 size whiteboards so that they could practice drawing these graphs. This proved to be very successful with students for the following reasons:

  • the novelty of using whiteboards
  • if they made a mistake this could be easily rubbed out and they could start again
  • it allowed me to go around the class to correct graphs where necessary
  • students took pride in their graphs
  • the best set of graphs was posted on the econfix blog
  • students who were struggling could learn off others
