Poll Everywhere is an audience response system (ARS) . Poll Everywhere allows you to poll or survey students in or outside the classroom, synchronously or asynchronously. Students can answer questions to polls or surveys with common devices like mobile phones, tablets, or laptops.
Students' answers can be anonymous or attributable, graded or ungraded. Participation and grades can be managed within the Poll Everywhere platform. Alternatively, grades can be exported into the Courseworks (Canvas) gradebook to manage these grades alongside other course grades.
You can find more information and create an account by going to the CTL website.
