In all seriousness, any conscientious designer who creates training or learning assets designed to influence human behavior or elicit change perpetually seeks the ways and means to make the content more compelling and more engaging.
There are several proven strategies:
Using video – who hasn’t learned how to do something by watching a YouTube video? Connecting learning to the bottom line – learners should be aware of the opportunity cost of them not knowing what we are trying to teach them. Unlocking the navigation – learners can move through the learning at their own pace, speeding through content they’re familiar with and going back to review when necessary. Mobile devices – content should be available at the point of need, and users are rarely very far away from their devices.
