What is microlearning?
Updated
Short answer
Microlearning is instruction broken into short, self-contained units, each covering one thing a person actually has to do and each finishable in a single sitting. On a frontline floor that sitting is usually 3-5 minutes on a phone. It is a statement about the unit of delivery, not about cutting total training time.
The unit, not the total
The term is often misread as "shorter training". It is really a statement about the unit of delivery. A microlearning module has a point, a check and an end. Five of them can add up to more minutes than one classic session and still work better, because each one can be started and finished inside a gap that genuinely exists.
That is a different decision from cutting a 45-minute deck down to 20. Splitting is not the same as re-authoring around single tasks.
Why size decides it without a desk
A person in an office can leave a course open across an afternoon. A person on a line, in a van or on a shop floor cannot. Their windows are the minutes before the shift starts, the pause between two orders, the wait at a loading dock. What does not fit that window is abandoned, and the record afterwards shows a start without a completion.
A Belgian retail chain rolls out a changed age verification procedure across 40 stores. As a 30-minute e-learning it competes with the shift. As three short modules with a knowledge check, it fits between customers, and the completion data arrives the same week rather than at the end of the quarter.
No rule sets a length for general instruction
No rule sets a length for general workplace instruction: Codex art. I.2-21 asks for training that is sufficient and adapted to the workpost, Arbowet art. 8 for effective instruction adapted to each task. Both ask for fit and effect. Specific regimes do set hours: Code 95 asks 35 hours every five years, in sessions of at least seven hours. If short modules reach the whole crew and a long session reaches half of it, the short format is the better answer to the legal test, not a compromise on it.
Where it does not belong
Microlearning does not replace practical training on equipment, a supervised first shift, or an experienced colleague standing next to someone. It is the format for procedural knowledge, changes and refreshers. The guide on why frontliners finish 3-minute courses and skip 30-minute ones sets out the mechanics.
