Polling and clicker questions are great ways to assess students’ level of understanding of course material and to further enhance student learning through peer instruction.

  • Consider resources needed to conduct your in-class activity. Some freely available software include Mentimeter, Kahoot!Some clicker options can be found here.
  • Prepare the polling / clicker questions. They are often multiple-choice questions (MCQs).
    • Good questions should enable students to apply their skill / knowledge; intelligible to everyone in the audience.
    • Correct answers should be unequivocally correct; and
    • Wrong answers should be unequivocally incorrect but seem reasonable enough for students to choose, should they have a misconception.
  • It is recommended that you keep student responses anonymous.

  • This activity can be done by individual students or in groups (competition-based).
  • Peer instruction, pioneered by Eric Mazur (Harvard), is recommended to be incorporated in this activity. To do so, first, allow students to answer the MCQs individually. After all responses are submitted, ask the students to discuss with their neighbours in class before answering again.
  • There should not be an overwhelming amount of questions asked in each class. One strategy is to ask a polling / clicker question after a new concept is introduced such that students can apply their knowledge. Another alternative is to introduce a new concept with a polling / clicker question to motivate learning.
  • Address any questions / misconceptions that arose during the activity.
  • Emphasise take-home message.
