If you do not know the answer or enter an incorrect one, WordDive will show you the correct answer. Below is the Spanish word fresca, fresh.
After clicking OK, you will write the word in the empty field. You might not notice it while you practice, but during this time you do not see the word fresca written anywhere. For this brief moment, the new word is stored only in your brain. The moment is very short, but long enough to activate the working memory memory.
Immediately after writing the answer, WordDive makes sure that you got it right and will also remember the word exactly right.
The brief moment during which the working memory is activated ensures that you will not copy the answers mechanically, but really learn them.
