Quizizz is an excellent student response system that allows teachers to provide a competitive classroom atmosphere. If you have ever played Kahoot, that to is a competitive game, but it can sometimes get out of control.
Quizizz lets teachers give out a quiz while keeping better control of their classroom. Each student will get randomized questions and will be taking the quiz at their own pace. Students can build confidence while taking the quiz with immediate feedback and not as many distractions as Kahoot. This program also does not need the use of a classroom projector to display the questions. All questions and answers will be shown on each students device (because all questions are randomized for each student). These quizzes can be played on any device with access to the internet.
You will find out when you sign up for an account that it is easy to use, a lot easier than Kahoot. After each quiz is given, results are shown with the ability to download them to an excel spreadsheet.
Lastly, to get an account for Quizizz, teachers do not have to sign up. They can search publicly made content to use in the classroom. But, if teachers want to create their own quizzes or view the data, they must make a free account. Make your own account here.
