Learning design in the workplace: why most training fails
The Ebbinghaus forgetting curve established at the end of the 19th century still holds: without revision or application, 50% of what was learned in training is forgotten within 24 hours, and 80% within a week. The main cause of failure of corporate training is not trainer quality, but the absence of a consolidation and application mechanism after the session. Learning design is the discipline that designs provisions taking these constraints into account.
The full-day training problem
The dominant format for professional training in France remains the full day in a classroom, or its e-learning equivalent: a long module, followed by a test, followed by forgetting. This format is designed for logistical convenience, not for learning.
Learning science (cognitive science, educational psychology) has produced over 30 years a convergent body of results on what promotes memorisation and skills transfer. Most corporate training practices ignore these findings.
What research says about learning
Spacing effect. Learning the same thing in several sessions spaced over time produces significantly better memorisation than a single long session with equivalent content. Six hours of training split into three 2-hour sessions over three weeks is more effective than a continuous 6-hour day.
Testing effect or retrieval practice. Forcing yourself to recall information from memory (by answering questions, solving exercises) is more effective for memorising it than re-reading or listening again. Consolidation quizzes are not gimmicks: they are the most effective mechanism for anchoring learning.
Learning in context. Knowledge learned in an abstract context is hard to transfer to a concrete context. Training anchored in participants' real work situations is systematically more effective than generic training.
Cognitive load. The human brain has limited processing capacity. A module that presents too much new information in too little time creates cognitive overload that prevents memorisation. The densest training is often the least effective.
The five most common causes of failure
- No diagnostic: everyone follows the same path regardless of prior attainment.
- No spaced retrieval: a single assessment at the end, no revision.
- Generic content disconnected from real tasks.
- No measurement of acquisition skill by skill.
- No manager involvement to enable transfer to the job.
What works
Short, spaced modules; retrieval practice embedded throughout; contextualised content; measurement of acquisition and transfer at 60–90 days; manager-supported application.
