@alvinauh, I understand it can be frustrating that your student has fallen asleep, but it's not always the teachers' fault. Unfortunately, teaching behind a monitor is not easy, students cannot interact as if they were in the classroom, they learn the notions passively and then the light of the monitor certainly doesn't help concentration and tires the eyes. But this pandemic forces us to change our habits and students will soon learn to manage their attention during these 3.0 lessons.
