I recently ran an Master-level course over Zoom with 82 students from 20+ countries. The course was carried out over a 5-day period and it was very intensive. Yes, the class started at 9am and ended late in the afternoon around 5pm, just like a typical class prior to the pandemic. With Presentria, I was able to engage my global students by not just asking them questions (6 question types), but also getting them to compete with each other using the built-in online activities (7 of them). The result? A super-engaging webinar that students appreciated. – Dr. Ken Wong
