We use this often on Purdue's campus in classes and programs that include a good mix of domestic and international students. If you are looking for an activity to encourage deep conversation about cultural values in diverse groups of students, this is a good pick. For this reason, I think it would work well with COIL/international virtual education (though I have never personally tried it in this context). Because it requires coming to a consensus as a group in multiple "rounds" of conversation, I think it would work much better with synchronous online discussions than spread over a longer time period asynchronously. Regardless of if you do this in person or online, pay close attention to the Notes tab, since there are multiple versions of the activity available for download and each has its advantages/disadvantages.
