Plickers combines high-tech (one smartphone with the recording application) and low-tech (printed on paper, cards for each student – 40 to 63 cards, and different sized cards for smaller classrooms or auditorium settings). The instructor creates questions, and then puts them in a queue, and performs a “Live View” which projects the question on a screen (project to a wall for your student audience). The audience can remain anonymous or you can create a class roster and Plicker will record the answer from each student.
“You print the Plicker cards in advance, one for each student
and record student responses
via your smartphone.
*I’m not sure if the application “bogs down” when there are a bunch of students, but it is supposed to record from 40 to 63 responses from all the cards being held up simultaneously. There does have to be a “line of sight” between each card and the phone recording the responses, so conceivably someone or something could block another student’s response.
Each card these students are holding has a unique outline. Each side of the card is lettered from A – D, and the student must hold the card so the correct answer is at the top of the card. *Scanning the responses takes a fraction of a second, so you don’t have to go up to each student to record their response. Also, you could record the responses from the back of the classroom, with students facing forward, holding their cards, facing backwards, and looking at the projected questions (from the “Live View” screen).
Here is a Plicker card #1 rotating through the various answers, A, B, C and D. Remember, the answer displayed at the top is the chosen answer. The smartphone screen capture below has recorded 7 responses, all “D” and the card numbers are in the upper left. Look closely and card 17 and 26 were being recorded with their response in the class picture.
