Learn forty German words on a Sunday and by Wednesday you'll have maybe twelve. The obvious conclusion is a bad memory, or not enough effort, and both lead to studying the same way but longer.
The research points somewhere less obvious. The forgetting isn't the failure. Spreading learning out over time beats massing it together, and it's one of the more solid findings in the memory literature.1
The Sunday session was the wrong shape
Forty words at once is massed practice. It feels productive, because during the session your recall is excellent. You've just seen the words.
That's the trap. How well you do while studying is a poor guide to what survives the week.
The same total time, split into shorter sessions with gaps between them, retains more. And the best gap scales with how long you want to keep the material.1
Rereading isn't studying
The second mistake is what you do inside the session. Reading a list of German words and their English meanings feels like learning.2
Testing yourself, trying to produce the word before you check it, works markedly better than reviewing the same material passively.3
The uncomfortable part is that retrieval feels worse. Straining for der Löffel and failing feels like proof you haven't learned it. That strain is the part doing the work.
What to change
- Fewer words per session, more sessions. Ten words four times beats forty words once.
- Always try to produce before you check. Cover the German, say it, then look.
- Stretch the gaps as words get easier instead of reviewing everything at the same rate.
- Attach words to something: an object, a place, a moment, rather than a row in a table.
That last one isn't from the literature. But the words that stick tend to be the ones met in a situation, looked up because they were needed, not because they were next on a list.
