  5. The length of duolingo course…

https://www.duolingo.com/profile/BigBang-O

The length of duolingo courses. A short summary.

I wonder very often about which courses have more content on Duolingo, for this reason I have done this short summary; a summary of the number of lessons, skills and checkpoints of all the english courses, and the average of lessons for skill for each course, and the average of all the courses for these 4 variables.

I would like to remark that this only measures the LENGTH of the courses, not the quality. A course can have less content but with more quality (with notes and tips, for example, or with more active moderators helping the learners). Not all that glitters is gold...

Maybe in some time I will add information about the number of words and words with images (I'm already searching information).

The tables: PD: The new greek tree has 278 lessons and 1288 words, according to griffpatch

The grafic of number of lessons:

Excuse me if there are mistakes, I'm not a native speaker.

-If someone can and want to add this information at duolingo wikia, it would be fine.

Interesting .. thanks for doing the work... I have started the German for English tree and I did notice that there were many many more skills than either of the other trees that I have done.. but that each skill had fewer lessons... nice to see a table that breaks it all down... Yes German does have more lessons.. but not THAT many more than some of the others.. Thanks again.

wow! this is so interesting! have a lingot!


https://www.duolingo.com/profile/Shahrazad26

Turkish may have less lessons but them lessons are difficult.


https://www.duolingo.com/profile/MattHaythem

They really are. I hope they expand it in the future. High quality Turkish materials are hard to come by.

Interesting stats BIGBANG-O. They do confirm some of my suspicions. I also still strongly believe that these features (the length of the tree, the amount of skills etc.) depend on many factors, such as when the course was created/released (which functions were available?) and whether it is the first or second tree version.

Thanks for calculating these aspects and for sharing them with us. :)

German update (accurate numbers)

My duome.eu profile page for the English-German course shows me (I have not bought bonus skills):

  • Skills: 121 + 2 (not 120)
  • Lessons: 458 + 4 (not 455)

https://www.duolingo.com/profile/DraganDer_Bratan

Thanks for your hard work, this was something i had been looking for


https://www.duolingo.com/profile/VictorTavares9

Thank you for your dedication to provide all this information. No Doubt it's very useful.


https://www.duolingo.com/profile/finndj

Greek has 278 lessons. :)


https://www.duolingo.com/profile/poche112

Now that this thread is a year old beware that the information may no longer be accurate. I know that they have added lessons to several courses in the last year. For example, I was working on the English for Spanish speakers course and had the tree finished when all of a sudden the number of lessons almost doubled.


https://www.duolingo.com/profile/BigBang-O

Yeah, actually when I made the thread some teams were already working on a new tree, so now it got a little old I guess... I would work to refresh the info but these months I am pretty busy, so it would be nice if somebody wants to gather up all the info and refresh it for duolingo students ;)

New Spanish-English (from Spanish) tree: https://forum.duolingo.com/comment/23545752$comment_id=28542155

  • 91 -> 151+3 skills

https://www.duolingo.com/profile/klaxonn

It would be nice if these infos were updated :)


https://www.duolingo.com/profile/81cheney

Dutch is exactly on the average along with Danish. I wonder why German and Norwegian have so many though. I'd ought to ask one of the course designers. Nice job either way.


https://www.duolingo.com/profile/ChadThunderbob

123 skills on German, even more on Norwegian. That's a looooooooot of space.


https://www.duolingo.com/profile/OsirisRivas

Yeah German is a very long course. I'll be so relieved once I complete it.


https://www.duolingo.com/profile/Shahrazad26

What is the meaning of checkpoints?

I was actually looking for this info as it will help me calculate how many hours of experience these courses provide. If, for example, I learn 200 lessons at 30 minutes per lesson (on exotic languages; easy languages can be done in 5 minutes or so), then the whole course will give me 100 hours of experience. However, I've been at it for 3 or 4 hours a day since March or so and I'm still not done.


https://www.duolingo.com/profile/Iul1

A check point is a test you can take so you can test out of or skip different skills. Each language has a few check points in its tree, so if you know the basics of a language, you can go to a check point and test out of the skills from that tree, up to that check point, but not past it. If you know more of a language, you can go to another check point and test out of more skills.

I hope this helps.


https://www.duolingo.com/profile/Gabrielle28671

I love this post so much info and so many languages


https://www.duolingo.com/profile/SurrealSoul

Concise and informative, great post!


https://www.duolingo.com/profile/Lento_Rodriguez

Very interesting post! Thank you!


https://www.duolingo.com/profile/DerLutz48

this is AMAZING, very interesting. Thanks for doing all this "number crunching"!


https://www.duolingo.com/profile/Esperantistino

This was very interesting. It also helps me understand why some people seemed to be taking an oddly long time to complete their trees. Theirs contain many more lessons than mine (esperanto, one of the shortest)


https://www.duolingo.com/profile/edo_farias

Excellent job done here. It would be amazing an update with the new courses, once a I did a similar post but from Spanish, https://www.duolingo.com/comment/23545752/Number-of-lessons-for-each-course-taught-from-Spanish

Norwegian update (accurate numbers)

Duome.eu page from Pat shows for the English-Norwegian course:

  • Skills: 117 (not 114)
  • Lessons: 531 (not 512)

https://www.duolingo.com/profile/Lars200

Is it possible that some courses have fewer lesson because those languages are perceived as more "exotic" i.e. spoken by small communities or far away from the English speaking heartland? Turkish, Ukrainian, Esperanto, Irish, Vietnamese and Welsh would qualify as "exotic" by this measure and they are all below average. Spanish (unexotic but below average) and Hebrew are outliers from this "rule" however.


https://www.duolingo.com/profile/MattHaythem

Norwegian is an uncommonly learned language in the Anglophone heartland, yet it has one of the most developed courses on Duolingo. Norwegian syntax is so similar to that of English that a lot of otherwise complex structures don't have to be taught because they're the same in the target language. This means the course creators can focus on vocabulary rather than grammar, which makes for a fun, easy and popular course.

Hebrew is another outlier. It's definitely not something most Anglophones learn, but a lot of people have had to learn it to immigrate to Israel. In order to literally bring a language back from the dead, teaching materials and methods have to have been high quality.

I think it might be a product of 1) the similarity to the learner's native language (Norwegian), 2) advancement of pedagogy (like in Hebrew) and 3) just sheer investment on the part of the course creators in making a high quality course like that of Turkish.

Turkish language learning materials for English speakers are next to non-existent. As far as books go, there's Teach Yourself and some dry book from the 60's which I somehow finished. In short, there's not much. That goes to show that the creators of the Duolingo Turkish course didn't have much to go off yet they still created something educational and engaging for a language very different from English. It may be short, but it's high quality.


https://www.duolingo.com/profile/DerLutz48

I don't that's quite right. If that were the case, French, being learned by the second largest number of people (after Spanish) on duoLingo anyway, should have way more lessons and skill than German. Know what I mean?


https://www.duolingo.com/profile/ZoeLanter

Very helpful! Thank you!


https://www.duolingo.com/profile/Iul1

Hi, can you please share the website for the duolingo wikia. And is that a duolingo site, or a site maintained by duolingo? Thanks, Iul1

Thanks for the info!
