Tree 2.0!

Goed nieuws, allemaal!

After a year and a half of work, the Dutch Tree 2.0 is finally ready to be A/B-tested. This means that 50% of you should already see the new tree. We’re very proud of it and think it is a huge improvement over the original course, which was launched in the summer of 2014 as the first Incubated course for English speakers. Some of the new features:

  • Over a thousand new words.
  • Many thousands of new sentences. We tried to be thorough when adding translations, but of course there will be some answers missing. Use the report button to let us know.
  • Smaller skills (max. 6 lessons) with smaller lessons (max. 6 new words).
  • More grammar-specific skills with Tips & Notes, especially early in the course: niet vs geen, je vs jij, word order, etc. Tips & Notes are unfortunately not available on your mobile. We will try to compile them all into grammar posts on the forum.
  • Many changes in the order of skills. Some small, some large.

Tree 2.0 FAQ

How long will the A/B test last?\ We don’t know, it depends on how clear the results are. Hopefully no more than a couple of weeks. This is not our call, by the way: the developers interpret the data and make the decision.

Will I lose my progress from the old tree?\ No, Duolingo will remember which words you already know. However, you will lose your trophy if you have it and most skills will require you to take one or more lessons with new words.

I want to try the new tree right away, can you put me in the test group?\ No, we are not able to move anyone between test groups. If you want a sneak peek, you could make a new account and hope for the new tree.

Can I do anything to help the new tree pass the A/B test?\ Whatever you do, it is unlikely to have a statistically significant effect on the results. However, the test mostly measures retention rates. So if you get the new tree, don’t get intimidated or discouraged. Give it a fair chance!

Are there bonus skills in the new course?\ No, we are still not able to add bonus skills.

What about the Words tab or the Fluency meter?\ We are not in a position to add these features to the website.

Where can I give feedback on the new tree?\ We will be reading this thread. For comments about particular exercises, use the report button.

Veel leerplezier,

Team Dutch

This is brilliant news. I would love to do it but I don't seem to be in the test group:(( I hope the testing goes quickly. I regilded my tree a few months ago and would really like to go further with Dutch. Thanks for your hard work :) Looking forward to the general release...

~120 incomplete skills... yay!!! :-D

Disappointed I didn't get the new version. I've been doing the same 'ol Dutch exercises for about 3 years or so now and I'm severely burnt out on it. Looks like they would give the new version to the ones who have been on the old one for a long time. In order to keep us practicing. I've started another Dutch account. It has the new version on it. This is the account I use. Hate to lose all I've worked for over the years but I came here to learn some Dutch not be test data. I don't understand what is accomplished by an A/B test if you force B to quit and become an A.

Tadaa :-D

That was incredibly refreshing, very enjoyable, a true pleasure!

Thank you Team Dutch. I've been waiting for Tree 2.0. Fortunately, I have the new tree and look forward to reviewing and learning more Dutch. The smaller skills and smaller lessons look learner friendly. Thank you. :)

Thank you very much for the news! When it gets to me, I better work hard to complete it and I might reach level 25 in the process :) I'm sure there'll be many great new words (starting now with "leerplezier" which I assume is pleasure taken in learning - I wish English had that as a word!)

All this discussion around the forums is making me impatient and itching for it to roll out :')

"Duolingo will remember which words you already know." So why do I have zero completed lessons in a skill that teaches words like "doei", "hallo" etc. when I had already finished the tree? I don't see a single word in the "Phrases" skill that I didn't already know.

Edit: Sorry, I just realised how whiny this sounds, but I am honestly just confused...

If you start re-doing topics where you know a lot of the words, the lessons will be very short and sometimes you'll skip several of them in one session, whereas I've noticed that in the later new lessons, where there are a lot of new words are more like the pace we're used to.

August 22, 2017

Sometimes it looks like it's incomplete, but there are one or two new words in that specific lessons. When you finish that lesson, it'll restore your gold.

Congratulations and thank you for all your hard work! I've been slacking on my Dutch lately, so this is a good reason to get back at it!

I'm in the test group. Initially was bummed to see my progress had depleted, but in going through the earlier lessons to build my progress back up again, I've been pleased to see the lessons are much more complete! I needed the pronunciation guide when I started months ago! Finally cracked the <<ben jij/jij bent>> confusion. Looking forward to having lessons on the day.

That's good to hear! :D
Good luck with your studies!
