Wooten et al. (2020) recommend the use of Kahoots to illustrate economics concepts.
Kahoot! is a game-based internet platform that can be used to assess students learning in the classroom. As described by the authors: "The setup of the system forces students to look up for the questions and answer options, while students registered their answers using an internet-connected laptop, tablet, or smartphone. If activated, instructors can display mid-game rankings and a visible leaderboard".
