By now, most of you have tried Kahoot!, the game-based student response system. The teacher creates a free account and then can create quizzes with embedded images and video. Students respond to the quiz using any device with Internet access. The faster they respond, the more points they score.
Kahoot! is lots of fun and really motivates students to participate. But what you may not know about it is the data that you can access once the quiz is over. After logging in, the teacher can access data from each quiz by clicking on the cloud download icon next to the name of each quiz. This will download an Excel spreadsheet that includes a detailed analysis of the student answers, including correct and incorrect answers by each student, along with an overview of how all of the students performed. This data is automatically generated and is a wonderful tool for formative assessment to guide instruction.
