Visualizing conversations in an online English class

Visualizing conversations in an online English class

Twice a week, participants meet in Zoom to practice English. The meetings involve small group discussions in breakout rooms where the participants speak with each other about a discussion prompt. Conversations last 5 minutes and involve 2-4 students. Over the course of about 8 months in 2023, there was a total of 278 separate small group conversations involving 52 participants from 21 different provinces across 2 countries. The meetings are free and open, so attendance varies by location as people find the class on their own or are invited by friends. However, most participants are in Vietnam due to efforts early on to advertise in Vietnam, and also the design of the class and content being made to suit a Vietnamese audience.
