Mentimeter is a nice service that allows you to pose a question to your audience and get instant feedback on that question through cell phones, tablets, and any other Internet-connected device. I reviewed the service a few years ago. Since then Mentimeter has added some more options for teachers.
The latest option added to Mentimeter is a quiz component. Like other quiz game systems, teachers create questions that students have to answer quickly and accurately. Mentimeter gives you the option to show immediate feedback on each question. There is a time limit that you can set for the questions. Students play along by either entering a quiz code on their phones, tablets, or computers or by scanning a QR code that you display to them.
Another neat response option in Mentimeter is the word cloud response. This lets you create an open-ended question for your students to respond to. Their responses are displayed as a word cloud on your screen. Mentimeter includes a profanity filter to preserve a classroom-friendly environment. Again, students join this activity by using a class code or by scanning a QR code.
Applications for Education
Mentimeter, like Socrative and Kahoot, is a good tool for collecting informal feedback from your students. You could use Mentimeter to ask students simple questions like, "do you feel ready for the quiz on Friday?" then use that information to formulate your next lesson plan. Tools like Mentimeter are also good to use as exit ticket systems at the end of a class meeting. Again, you can use the information collected through those exit tickets to influence how you design your next day's lesson plan.
