Most courses don't fail because of bad content

Let's be honest about what usually happens. Someone who knows their subject cold sits down to build a course. They dump everything they know into slides, record a few talking-head videos, add a quiz at the end, and ship it. It feels thorough. It feels generous. And learners quietly drop off around lesson three.

The problem is almost never that the expert didn't know enough. It's that knowing a thing and helping someone else learn it are two completely different skills. Teaching is design, not transmission. When you treat a course as a container you pour your knowledge into, you build something that makes sense to you and nobody else.

The good news: a handful of learning-science principles fix the most common failures. You don't need a degree in instructional design. You need to know where courses break, and build against it on purpose.

The core shift

Stop asking 'what do I want to say?' Start asking 'what do I want them to be able to do?' Everything in this course flows from that one move.

An expert builds a course by recording everything they know and adding a final quiz. Learners drop off early. What's the most likely root cause?
