This is a good way of getting to know students by name and understanding what makes them tick. Each week I get them to identify a number of roles based on their understanding of the assigned readings. These can be specific people, classes, ethnic groups, pathogens, resources, acts of God Students identify who they want to be. We then play through a number of scenarios that we collectively devise identifying which roles impact on others. Great fun.
Variation: Also had great results with objects – nothing like getting students to identify something and explain its wider social, economic and cultural associations. I sometimes combine the two activities.
