Jer’s Flash Card Viewer
I’m supposed to be learning Czech, see. I live in Prague, and it’s only polite to speak the lingo. So I’m taking lessons and making progress, but there’s so dang many words! To help myself review the vocab I wrote this little program and spent far more time than I should have tweaking the algorithm that prioritizes which words to show more often.
Flash Card Viewer’s features include:
- Adaptive prioritization focuses on words or phrases you are having difficulty with
- Words and phrases are grouped into levels, which can correspond to textbook chapters
- External library files allow easy sharing
- Easy to add and modify words
- Tracks mastery of individual words and phrases based on your criteria
- Ability to adjust word priority
Flash Card Viewer is for MacOS X 10.4 and later only.
Download the latest version of Jer’s Flash Card Viewer for Macintosh. This is a fully-functional version that you can use as long as you like. Every once in a while it will gently remind you that if you find it useful, to please pay.
Hey, it’s only five bucks!
If you build a library, it would be really cool if you shared it with others. There is a place in the forums to notify folks of your work.
Obviously I need to review how to say “jacket” in Czech!
For the propellerheads out there:
The algorithm for selecting a word is:
( log(minRandom) - log( (random() % maxValue) / (maxValue / (maxRandom - minRandom)) + minRandom) ) / ((log(minRandom)-log(maxRandom))/numberOfWords)
minRandom = exp(slider value), where the slider goes from 1.001 to 1.2 (user adjustable)
maxRandom = 0.27
maxValue = a very big number
Words are ranked by priority, and the priority is set at the start of a session based on word level, percentage, and the number of times the word has been shown. Priority is modified on each guess based on percentage and how many times in a row the student has got it right or wrong.
