This is a digital app that makes use of learners' cell phones (or other devices) for formative assessment through quizzes, multiple choice, T/F, polls, a "space game" and out-of-the-door “exit ticket” reviews. Games can be played individually or in teams. The app shows results in real time, charting answers of individual student results for each question, as well as a detailed chart of learner results for further review. Instructors can create rooms/groups students and classes for up to 150 students.
