4 Answer Buzzers

Cosmobuzz provides a clickable buzzer and a text entry field for answers.




Answer Buzzers are online multiplayer buzzers with buzz buttons that play a sound when clicked. The instructor hosts a “game room” that students join as players. Students’ buzzes are recorded in the order they occur.

Teaching Ideas

  • Put students into breakout groups to discuss a topic, solve a problem, or brainstorm ideas. Have the groups use the buzzers to indicate when they are done with their task and ready to return to the main meeting.
  • When watching a video demonstrating a specific topic or behavior, have students hit the buzzer when they identify it. For example, buzz when the video shows an example of force.
  • Use Answer Buzzers for a review game where individual students buzz in when they have the right answer.
  • To keep score, use answer buzzers in conjunction with a Scoreboard.

How to Use

Host a buzzer room and share its link with your students. After the students join your room, have them buzz when they know the correct answer to your question. Optionally, share your screen so students can observe the buzzes live.
