iClicker is a classroom response system that allows instructors to pose questions to students in class using a handheld remote. Students answer poll questions using their iClicker remote, and responses are transmitted to the instructor's computer. The instructor can then view response results in real-time. Setting up iClicker requires plugging the iClicker receiver into the instructor's computer, launching the iClicker software, creating a student roster, and having students register their iClicker remotes either in class or online. Within class presentations, instructors can use their iClicker remote to start polls, view response graphs, and advance slides. Student data is stored in iGrader for grading participation and performance.
