How I Use It
I tried this product as a test with just one class period. I used it as an engaging way to "survey" during a whole group discussion. After creating a "classroom set" of Plickers (I have 150 students - there is no way I would create 150 cards) and then assigning a number to each student, we began our test. Students reported that their answers were being reported back incorrectly. "Wait! I said 'A' - why does it say 'D'??" Sometimes the discrepancy was user-error but sometimes it was not.
Furthermore, the thought of what condition a classroom set of Plickers would be in after 150 students over time is not appealing.
I think this is a great product but not practical for me. I think it would work well if you only had 30 students.
