Audience response systems or Clickers are devices or phone apps that can change the class dynamics, allowing the tutor to hear from the whole group (rather than just the loud or confident students), to encourage ‘deeper’ learning (through peer instruction) and provide speedy, reliable feedback for both tutor and students about group and individual. Bruff (2012) and Beatty (2010) provide helpful frameworks that can help you design and run small group teaching in small, medium and large groups. Whenever you introduce a new technique or process into the classroom it is important that the reason for using it is thoroughly explained and expectations are communicated.
Whilst most of the research into the use of clickers and associated technologies have taken place in STEM subjects there is also a place for their use in the Social Sciences.
