But as soon as my streak ended, my frequency of playing went from 6 days in a week, to 5 days.. and now I haven't played it in months. Fake or not, keeping the streak alive did help me learn a lot of French (well actually there is one more side to it.. even after all that I can't speak a single proper sentence now apart from the basic je m'appelle stuff)
This is the real problem with Duolingo: it doesn't actually teach you to communicate in the language. Rote memorization and communication are two different things, and Duolingo does very little aside from drilling memorization. Streaks and gamification don't contribute to communication, which has its own system of rewards: when you communicate successfully, you accomplish some real-world task like buying yourself bread or getting a date, and that accomplishment doesn't need game-level rewards. Gamification is only effective when trying to palliate some sort of otherwise boring "grinding" (to use a gaming term from RPGs).
I’ve never tried it but I feel like it’s probably similar to Spanish classes in high school.
Duolingo doesn't put so much emphasis on conversation in my experience. Most of the questions give you the words in one language or the other and have you write out an answer. This allows you to lean on reading. Listening and speaking are the hardest parts so the should have the most practice, not the least.
If it's too easy, you can make it a bit more challenging yourself.
(I suddenly found myself stuck in Brazil for work for two months this year, and after a couple of hours of DuoLingo I was able to exchange a few phrases with hotel staff, often interspersed with the most useful phrase 'O que isso significa?' (What does that mean?')
The best part of DuoLingo was (and is) to save my conversation partners much of the 'Oh, in Portuguese we call that...' we'd otherwise be doing.
I think it's too dramatic to say it's a "real problem" with it! Anybody who intends to become fluent in a language is going to need to practice actually speaking and writing.
Is rote memorization essential to language learning? Absolutely. Should it be the focus of your learning after the very early stages? Probably not. It's just something you do, all the time. Memorize all you like, but true acquisition only comes after you've used your words in real conversation / listening, so that's should probably be where you place your effort. But that doesn't help Duolingo.
In the Japanese learning community, the seduction of this kind of rote, mechanistic, "streak-y" learning has been a trap for a long time -- so much so that there's a popular methodology that has people spend a great deal of time "memorizing kanji". It's appealing because Japanese has a big alphabet of complex characters and the methodology suggests that you can turn learning into a simple memorization exercise with discreet, measurable progress. The problem is, it's pretty much orthogonal to the act of speaking (or reading, or listening to) the language. Learn 2000 kanji and you might gain some ability to infer the meanings of words, but you're still essentially illiterate. The same thing applies at the level of words and sentences -- I have lots of words that I "know" on flashcards, but aren't available to me in actual conversation.
People get absolutely addicted to this stuff, spend years on it while gaining no meaningful level of language skill, then get frustrated and quit. The tragedy is that most people could put in a fraction of that time engaged in listening and speaking with a simple vocabulary, and end up in the kind of virtuous cycle that actually leads somewhere.
This is a more general problem with gamification and external rewards: they are just as good demotivators as they are motivators, if not more so.
This is why I wanted to turn off streaks when I was using Duolingo. I knew it was just a matter of time before I had my streak broken, and I was very concerned about what would happen then.
The gamification requires two coordinating motivations— secondarily the game mechanics, and primarily learning a language. Duolingo won't replace candy crush for non-language-learners. I imagine folks significantly discouraged by poor game performance without doing some serious learning first just aren’t motivated enough to practice their language skills in an app.
Personally, I’m not motivated by gamification at all and am content to ignore it. It is noisy, however, and I also wouldn’t mind the ability to shut it off.
That said, if you want to learn a language you need to study a lot. Complete everything Duolingo can in a few months and then find better courses of study to learn after that. You should never in my opinion have more than a 6 month streak.
It's similar to redit where someone demanded a subredit of mine since they deemed I not active enough (I was active but not to random guy's satisfaction) and the redit mods agreed. I haven't been on redit since after being a member for 15 years.
So yeah streaks, the chain (as Jerry Seinfeld says), consistency being broken makes me feel like crap.
