There is a U-tube video that I posted in a previous posting called ‘The Blah’ that would also apply here. Lecture has a time and place but we are learning for shorter times and not all places. In chapter 6, Brookfield talks about ways to keep your lectures effective and hold your students attention. He speaks to ‘chunking’ and buzz groups, both techniques I already to an extent use. Chunking is grouping or two thoughts together and only speaking on it for 15 min max. Then you engage the group into discussion on that topic and work in a supporting activity or assignment. This breaks your main theme up and provides more retention time for the material to sink in to the learner. This is very effective and I encourage you to work this into your lectures.
Are you chunking???
