I conduct hands-on, interactive workshops, which means there is a lot of discussion on any concept I teach, and after some discussion the attendees start coding.

I don't allow the computer to be open when we're discussing something in the classroom because it causes distractions. With laptops closed, they're fully focused, and when it's time for coding they can get back to their laptops.

I understand that different people have different learning mechanisms, but for trainings that I conduct, I've noticed a big difference in learnings when the laptops are closed.
