Learning objectives — after this module you will:
- Understand why knowledge from a classroom disappears so fast
- Separate a knowledge gap from an application gap
- Define microlearning correctly and spot the common misreading
Knowledge decays faster than you'd think
Face the problem with the one-off course model.
Hermann Ebbinghaus described the forgetting curve back in 1885: most new information is lost quickly after learning, with the steepest drop in the first days. This doesn't depend on the quality of the trainer — it's how memory works.
The consequence for corporate training: an intensive two-day course, even rated 4.8/5 right afterwards, leaves very little behind if nothing follows. The problem isn't the content — it's the programme's STRUCTURE IN TIME.
The spacing effect
For the same total hours, splitting the content and spreading it over time produces markedly better retention than massing it. It's one of the most robust findings in learning science, and it has a direct bearing on how you schedule a training programme.
Key takeaway: The forgetting curve costs massed courses most of their effect — the problem is the structure in time, not the content.
