I think this is one of the toughest problems I struggle with.
I often end up with some facts that are really important and unknown to the learner, yet too simple to make any kind of scenario exercise out of. Let's say you make a course on how to plan a party and you would want stuff like "Make sure to buy a cake", "Don't play dull music" and "Party hats can spice things up!" to go in there.
How would you present this information to make it as memorable as possible?
