The Problem with “Microlearning”
I've been in learning and development long enough to have championed terms I've since come to regret. "Microlearning" is one of them, and the regret isn't just about the term itself. It's about what the term has done to the field.
Let me be precise about what I mean, because the underlying logic that gave rise to microlearning was sound. Not every learning need requires a full course. Targeted content delivered in smaller units can support performance in the right contexts. Performance support — a job aid, a reference tool, a prompt at the moment of application — has genuine and well-documented value. None of that is in dispute.
The problem is that "microlearning" conflated that legitimate use case with something it cannot actually deliver: learning. Real learning, in the sense that produces durable behavior change, doesn't happen in small doses. The research on spacing and retrieval is unambiguous on this point. What works is repeated, distributed practice over time — the kind that requires effort and the productive discomfort that comes from being genuinely challenged. A five-minute video encounter with content is not that, however well-produced it is. It is exposure. Exposure and learning are not the same thing, and a term that implies otherwise does active harm.
The term itself is where the damage starts. "Microlearning" encodes a premise — that learning can happen at micro scale, that the dose can be small and still be sufficient — that runs directly counter to what the learning sciences actually tell us. Once that premise gets organizational endorsement, it becomes progressively harder to make the case for the kind of investment that actually produces results. I've written elsewhere on this blog about the corrupting power of permission — the way formal controls and institutional endorsements give people license to stop asking whether the underlying goal is being achieved. Microlearning, as it has come to be sold and deployed, is one of the most prevalent instances of that dynamic in corporate L&D today. The completion metric substitutes for the behavior change. The dose feels sufficient. It isn't.
It's also worth being direct about where much of the microlearning narrative comes from. The most widely circulated claims about its effectiveness tend to originate with organizations that have a direct commercial interest in the conclusion — learning platform vendors, content library providers, technology companies with products to sell. That doesn't make every claim wrong. It does mean the evidence base deserves more scrutiny than it typically receives before being used to justify an investment or a strategy. Practitioners who uncritically adopted the term gave those vendors cover they hadn't fully earned.
There's a professional credibility dimension worth naming as well. L&D practitioners have spent a long time trying to establish themselves as a function grounded in learning science — not content delivery vehicles, but practitioners of a discipline with real evidence behind it. The microlearning trend undermined that effort in two ways. It gave vendors cover to flood the market with content libraries dressed up as learning solutions. And it gave organizations a cheaper, easier alternative to the harder conversation about what development actually requires. If microlearning is what L&D offers, then L&D is essentially in the content curation business. That's a commodity. It's increasingly easy to automate, and it's difficult to defend as a strategic function with genuine organizational value.
The underlying instinct — meet people where they are, design for the context of application, don't over-engineer — is worth preserving. Performance support is a legitimate and underutilized discipline. Spaced practice, properly designed, is one of the most evidence-supported approaches to durable learning we have. Neither of those things requires the term "microlearning" — and both are better served without it.
The word has outlived whatever usefulness it had. It's time to retire it and replace it with language that's honest about what we're actually doing: either performance support, which is valuable and shouldn't be oversold as learning, or spaced practice, which is learning and deserves the investment it requires.
