"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. 

This activity draws attention to elements of conversation that may unintentionally contribute to, or exacerbate, conflict in otherwise civil discourse. By systematizing different types of pacing, participants are able to recognize their own preferred communication style as well as the cultural value of other preferred styles. The result often bolsters emotional resilience to interacting with others who have different pacing. This simple activity also allows for broader conversations of differing communication styles (direct/indirect, non-verbal etc).
