At the University of Illinois College of Medicine (UICOM), we have been exploring ways to liven up our educational sessions. With the advent of a new curriculum that has significantly fewer didactic sessions, and increased preparatory work by students leaves some holes to fill for face-to-face activities. One such example of gamification that we have employed recently is Kahoot!
Here is an example of Dr. Mahesh Patel using Kahoot! to encourage more interaction, and it proved to be a success.
We only use it sparingly, which I believe is why it is successful. Dr. Patel and I have worked together to figure out the best way to introduce it and when – the most success we have had with it is at the end of a busy week during a core case session. The students (and us!) are wiped out and it helps end the week on a fun note. We already use Poll Everywhere (probably too much), so this is a nice break from the ordinary.

There is a growing number of scholarly articles in the medical education literature about gamification, and I predict that will just increase. A wonderful colleague of mine, Bohyun Kim, has published extensively on this topic, from the perspective of the librarian educator.
