At Duolingo, our goal is to help learners build strong, lasting language proficiency. We use proven teaching strategies and continually assess our teaching effectiveness to make sure that our content sticks in the brain. Recently, we looked at our Review Exercises to see how well learners remember material. Here are a few helpful tips for learners looking to improve their recall during lessons!
Most lessons on Duolingo contain a series of exercises that teach our learners new words and concepts, but sometimes, we sneak in an extra exercise that comes from an earlier part of the course. This extra exercise is called a Review Exercise, and we use it to measure how well learners remember previous material. If a learner answers a Review Exercise correctly, we conclude they remember the material; if they answer it incorrectly, we conclude they have forgotten.
A Review Exercise is randomly sampled from the Animals skill and appears in a lesson in the Places skill. How the learner answers the Review Exercise tells us whether they can remember what they learned in Animals.
Our analysis suggests that moving forward to the next skills in the course may help reinforce recently-learned concepts. The learners who answered Review Exercises correctly had completed more lessons in the next skills than the learners who answered them incorrectly. This suggests that the next skills use and build upon the concepts learned in the current skill.
Our expertly-designed courses might make it feel like a game, but there is real learning science happening behind the scenes! Our learning and teaching experts use international language proficiency standards, the CEFR, to guide course creation, and we also use AI to adapt the difficulty level of your lessons based on your progress, so that you're seeing exercises at the right level for you.
Our lessons use interactive exercises to get you speaking, reading, writing, and listening right from the start. As you progress along the path, you'll work through more challenging exercises and will do even more speaking and writing in the language.
At Duolingo, we believe that staying motivated is one of the biggest challenges for learning a new language. In addition to creating world-class language courses to deliver great teaching, we also use gamification to help you enjoy coming back to your lessons.
Head to your profile (the person icon) and then the settings page to get the learning experience that's right for you: turn on reminders to help make studying a habit, and include speaking and listening practice in your lessons!
A lesson consists of a series of exercises that, when completed, yields XP. The number of exercises in each lesson varies according to the number of questions answered correctly: for each incorrect answer, additional exercises must be completed.
In the past, lessons were based on a heart system, where a heart was lost for each incorrect answer. This system was progressively replaced on Duolingo's various platforms in 2015 with the new strength bar mechanism, as described by Luis von Ahn:[1]
The lessons, exercises and courses are exactly the same as before. The new learning path simply organises them in a different way, providing a step-by-step experience that is intended to make it easier to reach your language learning goals.
For all intents and purposes, these are basically stepping stones, and each step has a different task and set of lessons to complete. Once complete, the level turns gold and you can move on to the next.
Hi everyone. I am going to rant. I am a super Duolingo user, with nearly 500 days and I had close to 400 crowns. Crowns were one of my main way of monitoring my progress.
The tree gave me the choice to hop to other subjects and slowly work my way through less favourable subjects or lessons that proved to be more challenging. Now there is no choice which greatly lowers my motivation. My yearly subscription is soon coming to an end and I am seriously thinking about LEAVING Duolingo for goods.
Also, my KEY Frustration is that it appears one can not TEST OUT or Level Up, by doing a lesson with fewer than 3-4 mistakes. This is an enormous difference! Sometimes a certain concept just comes easily, especially if you are studying multiple languages. (for example, my French helps me with my Spanish, on certain concepts like reflexive verbs with objects). So I HATE THE REPETITION if I already have the concept.
This upFor months now I have been managing a personal lexicon of vocabulary learnt from Duolingo. Without the ability to choose lessons, continuing to do this is nigh impossible. This update is detrimental to my learning ability, and may mean the wasting of months upon months of effort.
An awful update that is demotivating. The primary language which I was well advanced in no longer receives any attention from me. I have not done one single lesson in that language since the update. Considering I have a 1200+ day streak that alone shows how much I hate it.
The final unit exercise is also way too hard to get to Legendary. For people like me who wish to complete lessons fully (I.e. get to Legendary) before going to the next unit that really stalls progress. Simply because I am not allowed to practice individual parts thoroughly. I find this very demotivating. I really liked the way the other system worked because it allowed me to practice one specific part more.
Right now I am overwhelmed with the amount of new words thrown at me at once and the massive feel of the final unit lessons. I keep returning days (maybe weeks) on end to the final unit lessons with no progress and I find that highly irritating.
I am also brushing up on French. I studied it in college and lived in French speaking Geneva for 5 months. My placement in the old system put me in unit 7. I tried a few lessons and decided I needed a refresher, so I was doing the reviews at the end of each section, using the keys. It looks like I can continue my review using the Level Up feature.
One big concern I have is that i can no longer do lessons offline. There are many times that I am away from the internet for days at a time and I relied on the ability to complete offline lessons to maintain my streak. This is terrible, limiting, and internet-connection-elitist.
In the end I gave up on revising with Duolingo and dusted off one of my old German grammar books and within seconds found exactly what I want. And for my lessons on ordering food, I just went to Youtube and found dozens of great videos that far surpass anything Duolingo provides.
I absolutely hate this new path. I can barely stand to do one five minute lesson when I used to spend hours on it. I feel defrauded by Duolingo because I paid for super and then they switched to something I would never spend money on. The new path is trash and I will not be renewing my subscription.
I loved the old tree. As a language teacher, I liked the fact that I could pick and choose the language sections I wanted to focus on. The new learning path takes all the intelligence out of the learning system and you are stuck in a blind alley with no idea what the next group of lessons will focus on. This makes it really difficult to match Duolingo to my language classes. As Duolingo is primarily useful for vocabulary building, rather than as a full language course, this is an issue.
Have you ever been working on a lesson and, when almost finished, you ran out of hearts so you could complete it? But, of course, you can buy more hearts with gems. No gems? Then you can pay to get SuperDuolingo and get unlimited hearts!
I reluctantly put up with the above, trying to adjust my mindset and accept the changes. After all, it is a free product and Duo is entitled to do whatever it wants with it. But the ever increasing adverts between each lesson, prompting the user to take up the subscription, suggested a shift in company strategy. Still I continued. Diamond league for more than three years without relegation and no days missed.
None of this dissuaded me. In the beginning I went hard. I spent roughly an hour every morning, blasting through the early lessons. It was incredibly addictive. I had a baseline knowledge of Spanish (hola, amigos!) so I was breezing through with close to 100% accuracy, a gigantic ego boost that came with fuzzy feelings of achievement.
The big papa top league is the Diamond league. That's where the big boys play, but even getting to that point is challenging. These leagues are tough and some participants clearly have bugger all else to do but toil in the Duolingo XP mines. I discovered little bizarre techniques, just so I could compete. I'd rattle through lessons quickly, earn a 15-minute double XP boost, then maximize that time by rattling through the easy "story" lessons for 80XP a pop.
Honestly, when it comes to verbal practice, I think Pimsleur, a Duolingo competitor, is much better. The Pimsleur audio lessons ask you to say words or phrases and respond to a native speaker in the context of an actual conversation.
However, I do wish they included a little more instruction or explanation around grammar rules. It would be nice if Duolingo approached grammar sort of like how Babbel does it. Babbel integrates grammar instruction into their lessons in a very subtle and efficient way.
Thanks for posting this information. I am attempting to learn Turkish, and I did buy a simplified language course to expand my lessons. For the time being, I will continue with the free version of Duolingo. I do find it frustrating though when the pronunciation differs so much between the male and female voices.
I wonder if it is just me that hears this way?
We found out that, 8 out of 10 people use their smartphone during meals. Mostly to watch videos of kittens, fails, and other stuff.
At Duolingo, we believe they can spend their time better, by developing the habit of doing their daily lessons in order to learn a new language.
But sometimes they just need a reminder.
So, in partnership with Kellogs, we develop an everyday solution.
Because people never miss breakfast, and now, neither will their lessons.
