Alertness checks for continuing education credit

[afoley]

Hi all, I'm brainstorming ways I can implement alertness check during events that have continuing education credits associated with them. I know Zoom did away with their attention tracking but due to the accreditation body's rules we still need a way to verify attendees were actively paying attention to the webinar throughout. 

I think an obvious alternative is sending out poll questions, but our lead presenter doesn't like this idea. Does anyone have other ways they track attendee participation?
