Having trained thousands of people how to use Drupal since 2011, I've learned a lot about what makes students tick. Most of our classes have been in-person, since it's easier to teach effectively when I can instill enthusiasm by jumping up to the whiteboard, or rush over to help someone who's stuck. In wake of COVID-19 and the rapid transition to online learning, I'm reflecting how to make virtual training as engaging as it can be. I'd like to share four key factors for effective learning that go deeper than which video-conference or chat platform to use.
