Q: Can I ask a question spontaneously in class without having a slide written?
A: Yes, you can! i>clicker's "On the Fly" text box is available from within from the i>clicker floating menu bar so you don't have to quit your presentation to insert a spontaneous question. Your screen shot and question data are captured in i>grader for later review and point assignment. Note that you don't have to use the "On the Fly" function in order to ask a spontaneous question - it is simply designed as a convenience so you don't have to exit your presentation application. Many instructors simply ask the question (verbally or via the chalkboard) and then begin polling without formally typing a question into any software.
