Dry-erase answer boards, give every participant a voice and let every participant answer your questions. Trainers and teachers are able to gauge the entire class and see how well the whole group is doing.
Game show buzzers are unequaled in their ability to create a playful, exciting learning environment. The lights and electronics dazzle learners. Competitions spur engagement and team spirit, which is likely to remain with players long after a learning game. Their only downside possible is that they may limit the number of active players. In response skilled facilitators adapt their method of play to include the greatest possible number of players. Some choose to use phone-based buzzer apps like Meridia's CloudVote that allow every player to answer every question.
