YouTube Ethnography Project
While it was originally designed for study abroad pre-departure courses, Anthony Ogden's YouTube Ethnography Project is easily adaptable to a COIL context. Here is what I would do:
1. Put COIL students in diverse pairs or small groups.
2. Have them complete Step 1, creating their own videos. Alternately, they could find existing videos that represent their own culture(s).
3. Instead of framing their ethnographic research on YouTube as trying to under their host culture, have them search for and analyze videos related to the culture of their diverse teammates, including the videos those learners have already posted.
4. Team members can serve as cultural informants for each other, responding to conclusions drawn in the ethnographies when they are presented to the group.
