On a given Saturday, with time on my side and a bit of boldness, YouTube will teach me almost any skill. I need to change the oil in my car? 3,660,000 videos are ready at hand to show me how.
Great advice from the folks at Pathwright.com on designing courses by empowering your audience (your students or readers) with better questions they ought to be asking, rather than offering up only answers to the ones they already have.
Pathwright is awesome, too. Check it out!
