how does word strength work?
It seems like duolingo keeps my word strength at an abnormally high level. For instance, any time I have to mouse over a word to get the definition, it should hurt the word strength because it indicates I do not know the word immediately. Yet, to the contrary, mousing over words or even getting them wrong seems to have no effect on word strength, instead you merely have to get them right enough times and your strength will stay strong. Am I right? Can anyone tell me how and why word strength works as it does.
For instance, Memrise.com seems to do it more accurately, that if you miss a word once it goes back to low strength.
Also, I really hope they bring the vocab back. That was so helpful. Are they planning to?
Word strength doesn't automatically fall when you peek or get a word wrong. It also depends on how long it has been since you've seen a word. A combination of these factors work with an algorithm. (Not to mention, Duolingo seems to tinker with it from time to time. This post is 11mo old but it gives an idea: https://www.duolingo.com/comment/180620
If someone has a better answer, please post it. I know there is a really good explanation floating around out there. I just can't seem to locate it via the search bar. Thanks!
