Scenery, Machinery, People is an activity that we have been using at Purdue in various contexts - it seems really effective for encouraging self-reflection and empathy for others. In COIL/international virtual education as well as in study abroad, I think it makes students more aware of how they are treating others (and how that feels). To modify it for COIL, you could either assign a pre-reading or give instructions with the powerpoint in a synchronous meeting. Debriefing can be in groups via discussion board or individually in a reflective writing assignment. You'll want to be sure to focus discussion or reflective writing on the COIL experience via effective prompts, such as: when operating unthinkingly on "auto-pilot", when might you be in danger of treating others involved in this COIL experience as scenery? as machinery? how would you feel if others place you in that category? how can we intentionally work to treat each other as people in this course/program? how will this be beneficial?
