Foundations of Adult Learning

TL;DR; Adults don't learn the way children do. They come in with existing knowledge, they're skeptical, they need to understand why something matters before they'll pay attention, and they forget most of what you throw at them. Designing training that respects these facts is the difference between content people finish and content they quietly abandon.

This is the chapter where a lot of training projects go wrong. Teams design courses the way a university lecturer designs a course — long lectures, comprehensive coverage, quizzes at the end — and are surprised when adults in their organization don't engage. The reason is that adult learners are not university students.

What's different about adult learners

A few things distinguish adult learners from the kind of learners most of us picture when we think of "a class":

They already know things. They arrive with existing mental models, right or wrong. Your job is partly to build on what they know and partly to overwrite specific wrong pieces — not to treat them as blank slates.
They're busy. They're taking your course while also doing their actual job. Every minute of content costs them more than you think, and they will bail the moment they stop seeing value.
They need to know why. Tell a child "learn this because I said so" and they might comply. Tell an adult the same thing and they'll close the tab. Adults need a clear, honest answer to "why am I watching this?"
They learn best by doing, not by listening. Sitting through a 45-minute lecture leaves very little behind. Applying a concept to a real problem — even a small one — leaves a lot.
They forget fast. Not because they're bad at learning, but because they're not in a classroom where the next lesson builds on this one. They encounter your content once, maybe twice, and then it has to stand on its own against real life.

Every one of these has concrete implications for how you should design a course.

The implications

If you take the points above seriously, you end up with a very different course shape than a traditional curriculum:

Keep it short. Five-minute videos, not 50-minute lectures. Adult attention spans for passive content drop off fast, and a long video is not twice as useful as a short one — it's a quarter as useful.
Lead with the "why." The first 30 seconds of any video should answer: why does this matter, and what will the learner be able to do when it's over? If you can't answer that question, the video shouldn't exist yet.
Respect their existing knowledge. Don't explain things they already know. If your audience is engineers, don't spend three minutes explaining what a pull request is. Start where they actually are.
Design for application, not retention. Assume the learner will forget 80% of what you say. What's left should be enough to do the job. That means prioritizing: what are the two or three things this person needs to take away?
Close with something they can do right now. The biggest retention boost is applying the knowledge immediately. A 5-minute video followed by a 5-minute exercise teaches more than a 30-minute video alone.

"Less is more" isn't a cliché

The single biggest lever you have as a course designer is cutting. Every topic you decide to leave out makes the course more valuable, because it raises the signal-to-noise ratio for the topics you keep.

A common failure mode: you're writing a course and you have eight things you want to cover. You worry that if you leave any of them out, the learner won't get "the full picture." So you cover all eight. The learner retains maybe two of the eight — probably not the two you care about most — and the whole course feels overwhelming.

Instead: pick the two most important things. Cover them really well. Leave the other six for a separate piece of content, or drop them entirely. Your course is now four times as effective.

This is hard to do. It feels like you're cheating the learner by not covering everything. You're not — you're making the content actually stick.

The forgetting problem

If adults forget most of what they learn the first time, what do you do about it?

A few things that work:

Spaced repetition. Don't try to cover everything once. Introduce a concept in one piece of content, reference it in a later piece of content, and apply it in a third. Each encounter strengthens the memory.
Knowledge base over course, when possible. Some content is better as a reference someone can look up later than as a course they watch once. "How to do X" is usually a library item; "the big picture of how our system works" is usually a course. See Knowledge Base Overview for how Lupo supports this split.
Design for re-watchability. Short videos are easier to re-watch than long ones. A learner who needs a refresher six months later will happily re-watch a 4-minute video, but they won't touch a 40-minute one.

Where this falls apart

The masterclass spends a lot more time on the pitfalls — the specific places where well-meaning course designers ignore the above and ship content that doesn't work. A few worth mentioning briefly:

Assuming attention. "They have to watch this, it's mandatory." People with mandatory training click play, mute the audio, and do their actual work. You have to earn attention every single minute.
Assuming prior knowledge that isn't there. The opposite mistake: skipping the "why" because you assume the audience already cares. They don't. Tell them.
Optimizing for coverage instead of impact. "We need to cover all 12 topics in our SOP." No, you need the audience to learn the two topics that matter. Cover those. Reference the SOP for the rest.
