The Leitner System. The Leitner System is named for its creator, Sebastian Leitner, a German commentator. The system was first described in Leitner’s 2025 book So Lernt Leitner System. Leitner System is one of the most popular realizations of the spaced repetitions principle. It was developed in Germany in the 2025s by Sebastian Leitner.

The Leitner System — aka, the most efficient way to use flashcards.Spaced repetition, active recall, flashcards … put them all together and you get the Leitner System.The Leitner System is a technique for organizing flashcards that prioritizes studying more challenging material more often — until it becomes easy.The Leitner System: How it WorksBasic principlesGroup your flashcards into different categories (i.e. boxes) based on the difficulty levelRevisit the flashcards in the more difficult boxes more often than the easier onesRead more: Check out our guide to Study Strategies.Example way to set it up:Drawn in GoodNotesTake 3 boxes and label them: Easy, Medium, HardEvery card starts in the Hard boxAs cards become easier to answer, “promote” them into the Medium or Easy boxes. If you find cards are still challenging, move them back one difficulty level.Review the cards in the Hard box 3 times a week, Medium box 2 times a week, and Easy box once a weekVariations on the Leitner SystemSo long as you keep the basic principles of the Leitner System, you can customize it to work best for you.For example, to introduce more levels of difficulty, use more boxes. We recommend no more than 5, otherwise it can get too complicated.Read more: Check out our guide to Digital Planner stickers.Quick tips to simplify the Leitner system:Just use two boxes: hard and easy. The principle is the same: study the harder cards more often, and the easy ones less often. Depending on how you study, you may not need so many boxes.Use digital flashcards. The set up can be a hassle. Flashcards made in GoodNotes, for example, already employ the Leitner System in the background. They show you harder cards more often, and suggest a later study date to review them again.See digital flashcards with the Leitner System in action.Why the Leitner System WorksIntroduced by German science journalist Sebastian Leitner, his system for committing information to memory incorporates some of the strongest memory techniques:Flashcards themselves are one of the best ways to apply active recall when studying. When you work through the challenge of trying to remember something you’ve once learned, this is called active recall (also called retrieval practice). The process of doing so helps build pathways in your brain so it’s easier to find that answer in the future.However, it’s all too easy to cram a study session in with too many rounds of the same flashcards. At a certain point, you reach a point of diminishing returns, where each additional round becomes less and less helpful.That’s why the Leitner system calls for reviewing your cards once in several recurring sessions. This is called spaced repetition.In this way, each time you revise, you’ve taken a break from the material (thus forgetting some of it) and need to work to actively recall it back again.Lastly, you spend more time studying the material you’re unfamiliar with. By separating the “easy” and “challenging” material and studying them differently, it allows you to use your time more efficiently.Get Better Grades with Learning

Optimal time to review information is when you are just on the point of forgetting it. The Leitner System uses this phenomenon to support long-term retention as the review periods gradually increase. As indicated, I include 2 calendars and tracking documents (28 day and 64 day schedules) with this post. To implement the 28 day schedule, learners will need 5 boxes / 5 labelled folders / a box divided into 5 sections. Those using a 64 day schedule will have 7 boxes / 7 labelled folders / 7 sections in their Leitner Box.Rather than using separate boxes/folders, I created a Leitner Box using an old wooden box. I added tabs to some postcards and used these as dividers. Creating a Leitner Box of their own could be a good ‘up-cycling’ project for learners. Whatever is used, the Leitner System simply needs to be functional for each individual learner. It can be helpful to use an elastic band around cards in each of the sections to keep them organised or to prevent chaos if the box is dropped!As demonstrated in the 2 videos I posted previously, pupils begin by placing all their flashcards in section 1 of their box. Each day the cards in section 1 are reviewed and known ones move to section 2. Section 2 cards are reviewed every 2nd day with known ones moving to section 3. If an error is made, regardless of where it occurs, the card is moved back to section 1. This diagram demonstratesThe Science Behind the Leitner System - Leitner Box

We believe texting will continue to be popular in the future and will be endorsed by instant and OTT messages.We are looking forward to congratulate the SMS to its 30th Birthday. August 23, 2012 What Happened to Our Mobile Manners? Posted in Just for fun by Lisa Leitner Have you ever found yourself replying to a text message or an email during a business meeting or a dinner conversation? Let me tell you, Emily Post would not be amused with your behavior. Neither would she like to hear that 3 out of 4 adults text while driving nor that 63 % of Americans answer phone calls while going to the bathroom. However, this seems to be the inconvenient truth about our mobile manners of today.A recent survey from Online College shows that our mobile manners are not quite as sophisticated as we might think they are. It starts with the young (9 in 10 students text while they are in class), but likewise affects the old (15 % of all polled adults said they will answer a call while they devote themselves to the most beautiful matter in the world). We seem to forget everything our parents taught us about etiquette when it comes to our beloved smartphone.My personal favorite result is that 3 in 4 Americans use their cell phones while in the bathroom. For Emily Post’s sake please tell me you’re not reading this in the bathroom. August 16, 2012 Why we love text messaging Posted in messaging by Lisa Leitner From a 21st century point of view, text messaging might look like an old technology. With the revolution of apps you read headlines like “Text messaging is dead” or “Messengers kill SMS” on tech blogs every now and then. However, fact is that the long history of text messaging is one of the reasons why we regard texts as a reliable and pleasant way of communication. Our sympathy for text messages is so great that we might also say: we love text messaging.A survey conducted by Acision found that 92 % of smartphone users still send text messages. This makes texting one of the most widespread methods of communication in the world. Also, against all odds, SMS usage is increasing with about 8,000,000,000 texts being sent every day.Text Messaging Differences I – Women vs MenWhile both obviously love. The Leitner System.

This principle (albeit with fewer boxes) and the attached calendars outline the review schedule (for 28/64 days).In the videos accompanying the earlier posts, because the aim was merely to show how the system can be introduced to young learners, I solely concentrated on a set amount of content. With older pupils, the hope is the Leitner System becomes a core part of their study plan. To this end, it is important new flashcards are added to box 1 regularly. Students might start with adding 5-a-day, gradually building up to adding more and more cards. Some learners find it useful to purchase coloured flash-cards and colour-code according to subject; this is personal preference.At the outset, it is useful to allocate some class time to the creation of flashcards. This may be particularly helpful if pupils are struggling to identify key information and apply the minimum information principle. Because the Leitner System is such an effective study method, lots of apps have been created based on the concept of using flashcards for spaced practice. The original of these, Supermemo, was created by Piotr Wozniak. He created an algorithm now used by many of the other apps. As well as Supermemo, here are some other flashcard/spaced retrieval study apps. Some are free while others may charge a fee or offer upgrades at an additional cost.Anki, Brainscape, Cram, StudyBlue, StudyStack, and Quizlet.There are also specific language-learning tools, e.g., Duolingo.Included below are images of the 28-day and 64-day Leitner System trackers.

Having examined how to use CardEd to introduce the Leitner System to young learners, I want to consider how to use it effectively with independent learners.You may recall in my first post on the topic, I advised having one piece of information per card. This is known as the minimum information principle. Adhering to this principle reduces the risk of students mistaking recognition for recall and tricking themselves into thinking information is known/understood simply on the basis that they are familiar with it.Flashcards might have:A word on the front and the definition on the back;A question on the front and the answer on the back;The name of a mathematical formula on the front and the complete formula on the back;An acronym on the front and its meaning on the back;A date on the front and a significant historical event on the back.A country on the front and its capital on the back.Previously, I considered the Leitner System from the point-of-view of a teacher implementing it at school, i.e. operating on a 5-day week. In today’s post, I include schedules over a longer time-span (28 days and 64 days). This is because the Leitner System is based on the theory of spaced repetition. Gradually increasing the time since a topic was last reviewed creates a desirable difficulty by making it harder to recall the information. This retrieval difficulty serves to increase the storage strength of the information and actually makes it easier to recall it next time it is reviewed. TheThe Leitner System - dumondeducation.com

2025-04-21Updated by Kamika Royal on Sep 10, 2024 As with all other pieces of technology, you may encounter glitches or other small issues while using your Leitner headset. Here are some basic troubleshooting steps you can take to efficiently get it back up and running.Before doing any testing, please ensure that the headset is powered on. You should see a blue light on Leitner Premium Plus headsets and a white light on Leitner Premium Lite headsets.No Mic AudioPhoneCheck the connections. Verify that the green cord in the TEL jack is fully connected to the phone (not loose). To test this, unplug both ends for 5 seconds, then plug back in. Also try reversing the ends of the connector cord. Plug the green sticker end into the telephone and the other end into the base to see if this changes the sound quality.Check the compat on the bottom of the headset base. The most common compat settings are 1 and RHL. Try moving the slide down to 6, then back up to 1 to ensure it's on 1.Make sure headset is not mutedIncrease mic volume using the buttons under the baseTry using the curly cord from the handset in place of the connector cord that plugs into the green PHONE jack on the Leitner base. This will determine if the issue is a bad connector cord.Resync the headset and base.
