"Pacing" is a great activity for diverse teams to increase the effectiveness of communication and improve team dynamics. We use it often at Purdue both for on-campus courses and in preparation for study abroad (for example with students who prefer turn-taking but will be immersed in a host culture that uses overlapping). When you have a COIL/international virtual education program that will involve students from different communication styles, this activity would be very good preparation for students. I recommend doing with with all groups of students involved in a program in person before the experience begins rather than trying to adapt it to an online medium.
