I would give all my lingots...
... just to understand the algorithm for the decay rate, or to know how to 'practice' more than one skill at once consistently. ALL. MY. LINGOTS. and my first-born.
Honestly, the decay rate makes no sense. Especially for basic stuff. I would not repeat Kindergarten just because it's been a while. So I'm not going to repeat the basics of the language when I've got them down-pat either. I'd rather just ignore the golding system altogether.
Well we now know what kat would do for knowledge. And it seems the answer is 'just about anything'. A dangerous offer ;-)
Nobody knows for sure the full answer to that which you seek, but I can tell you this:
- the less you practise a skill, the faster it decays
- when you practise a skill, the more answers you bungle, the faster the skill decays
- the more words you look at the hints for, the faster that word decays
- the more words in a particular lesson that decay, the faster the lesson decays
As for your other question, the answer is of course, "practise". Practise, practise, practise, until you're bored of a topic. Being bored of something is, in my experience, a good indication either that you haven't a clue what you're doing, or more likely that you know something inside out. So when you're bored, move on to something else. The more you practise a variety of topics, the greater your knowledge of those topics will be. That's why your skills decay, to prompt you to keep practising. And to keep you hooked on Duo of course...
Now, I believe I was promised several thousand lingots. You can keep the baby, as I have no need for one of those.
Whoa, here have this baby.
Kidding! So, I thought that it worked according to your points above. However, I'm particularly frustrated right now because French is my strongest language other than English (I'm Canadian eh) and when I log in there will be 6-8 lessons to go over, even though I find the Duo french kind of easy. So perhaps it's hitting hard on the first point- who knows.
I know that keeping those lessons gold shouldn't be the focus, but at the same time these lingots are really quite useless. :P Have ten!!
I think it had been established that a skill is gold as long as its words have an average strength of more than 2.5/4. (i.e. the strength of a skill depends only on the strength of its words, and words decay, as you described, faster when you get them wrong or use hints).
The thing is they are probably constantly tweaking the algorithm to improve it. So it is a moving target. They seem to be balancing learning efficiency against user engagement.
If anyone here is only interested in learning efficiency then they should check out SuperMemo. However, I think most of us are here because we need a little gamification to motivate us in our language learning. So that means becoming lab rats while Duolingo tries to work out what is best for us all collectively.
SuperMemo supposedly has the most sophisticated algorithm. However recent versions costs money and it had a reputation for being quite buggy - not so sure if this still applies now though. It is the heavyweight in this area, and needs to be considered by anyone who wants to really optimise their learning efficiency. The whole "surrender to the algorithm" thing seems a bit grim though.
Mnemosyne and Anki are based on a early versions of the SuperMemo algorithm, and are free (as in Open Source), if you would prefer to try them. Most people do this, rather than take on SuperMemo.
It is a beautiful thing when you finish a lesson and find out you strengthened two lessons. I gave you one more lingot in hopes that it helps you with your quest for knowledge.
Haha thank you but I have thousands.... all USELESS in my fruitless attempt to keep my lessons gold. Here's one back! :)
mind blown yup, there's probably an analogy in there about money and happiness!
Thousands!? How often do you practice!? I'm here for 5 hours a day minimum but sometimes life gets in way and breaks my streak. I dont just use the functions here but take breaks to look at sources outside of here. I'm so envious of your streak. ):
Every day! I have REALLY found that doing a little (10-20 mins) every day works a lot better for me, and then of course speaking as much as possible and using other resources. I built up a lot hoping that Duo would roll out more features on which we could spend them.
This is exactly what I do. Im actually on here for more than 20 minutes though, hours usually. But the thing is I always stop mid course to study/look up terms and how to use them then go back. Its a bad habit but I'm also trying my hardest to 'remember' and keep words to memory, its not as easy as it seems! Maybe I'll catch up with you and pass your level on French, I'm not that far away! >:D
Ah the French tree. I deleted it when I was finished because I was sick of keeping it up (and wanted to brush up on my Polish), but now I added it back and regret it. haha
Recently i decided to create an excel file with all the skills and began to record how many times I have to answer to complete a strengthen skill review. I am giving them colors, e.g., from 30 to 39, yellow color. I found this very helpful to assess my progress and at same time to keep track of which ones i have more difficulty. I was also pleasantly surprise as the Duolingo algorithm seems to be balance and doing a pretty job in tracking my weak spots.
I haven't practiced French in awhile, and tonight I did one lesson. When I finished I suddenly strengthened 3 lessons!!! It's a personal record and I knew you would appreciate it.
Noice. I remember one glorious time that I strengthened 4 German skills at once. It never happened again, and now I'm not even sure it was real.
Four is epic. In the future children will sing songs about you. Old people will tell their tales to children and grandchildren about the days of Duolingo and Legend of Kat and the four gilded skills. :)
Two more practical things: The chance to strengthen more than one skill at the same time is bigger when you start strengthening the newest skills and work your way upwards. Do some rounds of flashcards before you work on the tree. This is good for strengthening words and keeping the tree golden. It is not so good for real learning.
Once I figured out that peeking was penalized I stopped doing it. I also figured out that the more mistakes I make, the faster the leaves get gray. Duolingo makes me do the difficult lessons over and over.
What happens if I decide to completely ignore fading gold? Will I run into trouble later? In my first two weeks I didn't know I was supposed to redo the skills and the new skills stopped opening up until I figured it out. So is there a certain level you have to reach before more skills become clickable? If not, I'm going to start ignoring fading gold leaves as they are slowing me down too much.
I have been using duolingo for 230 days (continuously), what I always do is use the strengthen skills option (daily) at-least for 100 xp (I think it gives you the skills which you didn't practice for long time or which you have not scored well in the past). Whenever I get bored of the usual stuff (usually after 10-12 days after learning a skill), I go for learning a new skill.
This system is in place for you to excel in the language, please don't avoid them (my request). Till now I have never lost the gold system, Hope it helps for you too.
I've really struggled to find out, but failed miserably.
I've done a small test, I restarted my Spanish tree using a new account. For some reason when I finished "Verbs: Present 1" (that's 3 lessons) I'd only learned 2 new words when looking at the words list. I'd had had plenty of lessons with walk, pay, run, cook, want and more but for some reason these words did not show in my words list. For most other skills the number of new words learned is quite a bit higher when you finish it. Also Duo will keep asking for some words that you may know very well (because it just keeps asking them!) while others are hardly taught at all and consequently I hardly know them.
I really feel the algorithms need some serious upgrade. DL is free, also mostly free of advertisements, I really like and appreciate that, but still it's irritating that it doesn't work better.
