How not to forget this word
Reading a word and remembering it are different jobs. A day later, little survives of a single reading — and that is not bad memory, that is how memory works.
- This has been tested on foreign words too. The difference shows up most when you test yourself a few days later rather than straight away.checked many timesKim & Webb, 2022, Language Learning 72(2) · 48 experiments, 3,411 participants, 98 comparisons.
- Recalling beats re-reading. Covering the translation and trying to remember it does more than reading it ten more times.checked many timesAdesope, Trevisan & Sundararajan, 2017, Review of Educational Research 87(3) · 188 experiments, 272 comparisons. g = 0.61; against plain re-reading 0.51, against passive review 0.93.
