Microlearning that actually sticks: lessons from the forgetting curve

In the 1880s the psychologist Hermann Ebbinghaus tested his own memory with lists of nonsense syllables and found something every training manager has since rediscovered: most new information is lost within days unless it is revisited. His forgetting curve is more than a century old, and it still explains why a full-day workshop often changes very little by the following month.

Microlearning is frequently sold as the cure. Make content shorter and people will remember it. That is only half true. Short content is easier to start, but length alone does nothing for memory. What helps is how the short pieces are arranged over time.

Spacing beats volume

Research on the spacing effect is some of the most consistent in cognitive science. The same total study time, spread across several sessions, produces far better retention than one long block. For a workplace programme this means a five-minute lesson every week across a season is more valuable than a two-hour module in week one.

Retrieval is where learning happens

Re-reading feels productive but is weak. Being asked to recall something, through a quick quiz, a scenario or a game, strengthens memory far more. This is why we pair courses with play: a short team challenge that asks people to use what they learned is not a distraction from training. It is the training.

Context makes it relevant

A retail floor manager in Durban and a software team lead in Pretoria do not need the same examples. Content that reflects real situations, local customers and familiar language is easier to transfer to the job. Our catalogue is built with sector collections for this reason, and custom content can be added where a generic course would miss the point.

• Keep lessons between three and seven minutes.
• Release them weekly rather than all at once.
• Follow each lesson with a quick recall activity.
• Use local, role-specific examples.
• Revisit key ideas later in the season, not only once.

Measuring what matters

Completion rates tell you who clicked. They do not tell you who learned. Pair completion with assessment attempts, scenario scores and, where possible, an operational signal such as fewer support escalations. We go deeper on this in how to measure engagement without vanity metrics.
