Steps:
- Pose a question to the class and give them a moment to formulate an answer.
- Randomly call on a student, giving them three options for their response:
- Answer - share their answer to your question with the class.
- Pass and answer later - give the student more time to think and return to the question later (if reasonable for the class), or you could return to that student later to answer a different question.
- Ask you a question - request clarifying information about a piece of your question they were confused by. After you answer, the student could attempt to answer the original question, another student could be called on to answer, or students could discuss the original question in groups.
- Incorrect answers from students should be handled warmly (for example, by pointing out good things in their response). You can follow up by asking a simpler question that highlights or addresses what mistake they have made or having the class discuss the question with neighbors and inviting the student to try again after getting peer input.
Methods for randomly selecting students:
- Assign a number to each student (or each student-group) and roll dice or use a random number generator to select students.
- Put student names on notecards and randomly draw a card. If you ask students to create these cards for you, you can also ask that they share information about themselves with you - interests, experience with the subject, career goals, pronouns, etc.
- Randomize name order on your class roster and call on students in order on this list.
- Use an app, website, or program to randomly select from your student list. Be careful with inputting any FERPA-protected information.
- You don't have to do the selection "live" - randomly select some students before class and bring that list of students to call on during that session.
Value: Invites students to apply and discuss material while fresh in their minds, provides immediate feedback about student understanding, makes space for more voices to be heard in class
Variation (Group Random Call): After asking your question, let students chat in groups about their answers. Then randomly call on a student and ask for their group's consensus. In addition to the response options above, also allow students to have another member of their group answer instead. This variation closely follows the proposed critical components of random call given in Waugh and Andrews (2020), see below.
Variation: Use random call after as the conclusion of another activity type - have students explain their reasoning after answering a multiple choice question, use at the conclusion of a think-pair-share activity, to solicit ideas following group discussion, or ask students to read responses after a minute paper. You could repeat random call a few times after the activity to hear multiple points of view.
Variation: If students are working in groups, call on a group randomly instead of individual students. Which student in the group share the group's answer could be determined by the group itself, selected randomly, or chosen on a rotating system.
Variation: Allow students to request to join a "do-not-call" list that will remove them from the random selection process. Instructions for joining the list (or removing themselves) should be clear to students.
Note on Random Call: Research on random call does confirm your suspicions: random call can give students anxiety. But research also identifies that students feel it helps keep them engaged, complete pre-class work, and actually attend class. The research also shows that students' anxiety lessens with experience, random call reduces gender-gaps in class participation rates, and employers want students to learn speaking skills in college. Balancing those benefits with easing student anxiety can be done with well-planned random call techniques as described above.
