Students in our most advanced level write a research paper as their final writing project each semester. In addition to turning in a written paper, the students also prepare a poster presentation based on their research. When students presented their posters face-to-face, they were asked to dress up, members of the university community were invited to attend, and all students presented their posters simultaneously while attendees moved from one poster to another (similar to TESOL poster presentations).
I'm sure others in the TESOL community have done similar projects. How are you moving this kind of activity online?
