Teaching large groups is commonplace in UK HEIs, and it’s likely that at some point or another, most academics will face this situation.
In this video Graham Gibbs talks about the realities of large group teaching in lecture theatres, from acoustics and echos to engagement and attention spans. He talks about the pressures this style of teaching puts on faculty, the lack of feedback and visual clues about understanding, and how isolating and unrewarding it can be as a teaching experience.
He goes on to suggest ways the problems he identifies, problems we all face teaching large groups, can be addressed, and how the situation can be improved. In turn this can lead to a more active learning environment, more imput from students, and more successful meeting of learning objectives.
