Then you must try Quizalize. Similar to Kahoot! yet you don’t need a projector and you can set up the quiz and let the students complete the quiz on their own. You can see the results (per student as well as class-wide) and can quickly pinpoint which questions caused the most trouble. There are not as many premade quizzes (at least not yet and there is also an option to purchase quizzes). For a thorough review of Quizalize, please see Amy Roediger’s blog post here (from A Lever and a Place to Stand).
