An opinionated critique of Duolingo

I've tried learning apps with LLMs and part of the issue is that you can't have much of a conversation early on. A conversation of "how many cats do you have?" "I have two cats" "what color are your cats", etc., isn't much different than the non-AI lessons. At the point where it would be really useful, the other options you mentioned are much better choices.

I can relate to this post - great thoughts!

I took Spanish in high school and college, so had a rudimentary understanding of verb tenses and some vocabulary. Before I walked the Camino de Santiago el Norte (45+ days in Spain), I used Duolingo to brush up on my Spanish.

It helped my reading most, my speaking a fair amount and my listening/conversation the least. I was able to ask questions, but was often flummoxed at any reply that wasn't the most basic.

I grew to hate the gamification, but was addicted to my "streak' also ... using math lessons when I didn't feel like doing a Spanish lesson. The so-called "leagues" were kind of useless since the same people weren't in the league from week to week. Any friendly competitiveness to "learn more" was lost when randomly assigned to a different group each week.

I finally abandoned the app this spring.

I'm trying Babbel now since I'm going back to Spain for a month and Patagonia next year.

Both of my parents are teachers of a European language. They both have phd's in linguistics, and rate very highly with students (who basically adore them).

All of this context to say that not once has anyone using Duolingo been able to "test out" of the first ("101") class that they teach. Duolingo self-learners come in with a very unequal mix of vocabulary and... not much else. Unable to use declension properly [0], unaware of most rules around gender, verb tenses, etc.

I'm sure (and I should look it up) that there have been academic papers written on these quite different methods/approaches: gamified learning vs "academic" learning, immersion by moving to a country, etc.

But in my parents' experience of teaching (which spans ~40 yrs), Duolingo students pretty much all became disappointed in the app: these students thought that they had developed skills when it turns out they mostly got addicted to a game that overpromised useful learning over entertainment.

Imho, the ugly truth is that language learning as an adult is deeply hard and requires a tremendous amount of effort and "tricks" to keep yourself motivated. People who watch native media with subtitles, play with AI apps (such as the YC backed https://www.issen.com/ which is quite nice), take a mix of "classic" classes, spend time in a country where the language is spoken and force themselves into situations where they "have" to speak, etc. all do much better. But it's a ton of effort.

I have a 2000+ day streak on Duolingo, mostly learning Russian. The app has got progressively worse since I started, for a while just giving me the same lesson every single day. I of course finished the course years ago, but I keep up with my one lesson a day to keep the bird happy. I find the UI incredibly annoying, I've disabled all the sounds and animations that I can. You might ask why don't I stop? Well I want to keep up my Russian, and the one lesson a day keeps my brain ticking over.

Anecdata: my daughter, when a rising high school sophomore in 2023, used DL to skip a full year^1 and join upperclassmen in Spanish 3. She went on to take AP Spanish, earn college credit w/ her AP test score, and join the Spanish National Honors Society. She credits DL w/ giving her the confidence -- and vocabulary -- to make the leap when she did. Of course that doesn't mean critiques aren't valid, and YMMV, but it does help show that DL isn't necessarily useless, either.

1. Despite US high-school language classes generally having a (usually deserved) reputation for failing to impart real fluency, our town's language instruction is actually first-rate.
