I did this activity recently with staff in a virtual environment and it worked very well. I would say that the time estimate is conservative. You might be able to do it in 45 minutes with a small group and only if they were thoroughly familiar with the reading beforehand. We had 60 minutes and were wishing for more because the group was so engaged and talkative. I would especially recommend the activity for frontline workers in the higher education context - advisors and other staff in contact with students. My recent participants indicated that they found the activity very helpful for developing cultural humility and becoming more aware of the microaggressions that Asians and Asian Americans experience. What we didn't have as much time for, and what they were really longing to talk more about, was more on what to do when they witness these phenomena.
