Kahoot! is a game-based learning platform available at no cost for educators. Each Kahoot! is a multiple-choice quiz that allows instructors to review student knowledge or break from the traditional “chalk and talk” lecture. A Kahoot! can also be used as a basis for formative assessment. Quizzes can be accessed by students on a tablet, phone, or computer, but are designed in such a way that encourages social learning so that students must frequently look up from their devices. Kahoot! is one of a number of personal response systems and it offers some particular advantages: students find it engaging, there is no cost to instructors or students, there is no account setup by students, and it is based on gaming philosophy. Kahoot! lets users share games created by individual users, a handy feature that allows work to not only be replicated but modified by other users. The Kahoot! games mentioned on this site can be used with other personal response systems (iClicker, Poll Everywhere, Trypingo, Directpoll, etc.) if the user is willing to transfer the questions into a new system.
