What could you do in a space like this?
Large groups can pose challenges to assess understanding and keep students engaged. Even relatively run-of-the-mill and unremarkable teaching spaces can lend themselves to some simple techniques to help you maximise student engagement.
This suggestion sheet from BCU offers ideas that you and your course team might like to try out and then evaluate as part of you own practices. For example, you can try post-it notes to support AFL/AOL (assessment for learning/assessment of learning) by asking learners to recap a concept or generating ideas and placing them on the wall.
