A quiz straight after the briefing
While everyone's still in the room.
- The question on the big screen, the answers on phones.
- The answer after every question, with an explanation.
The same quiz again a week later
Spacing it out works better than cramming it all in at once.
- Missed questions can come back after seven days and again after 30.
- The report shows which questions need another look.
The research behind it
Two studies in real workplaces.
- Employees who got quiz questions in the training video remembered 26% more the next day than those who just watched it. Okano et al. (2018), PLOS ONE 13(10)
- Spaced repetition works in workplace training too: the longer people need to remember something, the longer the gap should be. 10,514 employees in five organizations. Kim et al. (2019), Behavior Research Methods 51(4)
