A flashcard or flash card is a card bearing information on both sides, which is intended to be used as an aid in memorization. Each flashcard typically bears a question or definition on one side and an answer or target term on the other. Flashcards are often used to memorize vocabulary, historical dates, formulae or any subject matter that can be learned via a question-and-answer format. Flashcards can be virtual (part of a flashcard software), or physical.
Flashcards are an application of the testing effect − the finding that long-term memory is increased when some of the learning period is devoted to retrieving the information through testing with proper feedback. Study habits affect the rate at which a flashcard-user learns, and proper spacing of flashcards has been proven to accelerate learning. [1]
Flashcards exercise the mental process of active recall: given a prompt, one produces the answer. Beyond the content of cards, which are collected in decks, there is the question of use – how does one use the cards, in particular, how frequently does one review, and how does one react to errors, either complete failures to recall or mistakes? Various systems have been developed, mostly based around spaced repetition – increasing the time intervals between reviews whenever a card is recalled correctly.
Spaced repetition is an evidence-based learning technique which incorporates increasing time intervals between each review of a flashcard in order to exploit the psychological spacing effect. Newly introduced and more difficult flashcards are shown more frequently while older and less difficult flashcards are shown less frequently. The use of spaced repetition has been shown to increase rate of learning. [2] Although the principle is useful in many contexts, spaced repetition is commonly applied in contexts in which a learner must acquire a large number of items and retain them indefinitely in memory. It is, therefore, well suited for the problem of vocabulary acquisition in the course of second language learning. Spaced repetition software has been developed to aid the learning process. [3]
The Leitner system is a widely used method of efficiently using flashcards that was proposed by the German science journalist Sebastian Leitner in the 1970s. It is a simple implementation of the principle of spaced repetition, where cards are reviewed at increasing intervals.
In this method, flashcards are sorted into groups according to how well the learner knows each one in the Leitner's learning box. The learners try to recall the solution written on a flashcard. If they succeed, they send the card to the next group. If they fail, they send it back to the first group. Each succeeding group has a longer period of time before the learner is required to revisit the cards. In Leitner's original method, published in his book So lernt man Lernen (How to learn to learn), the schedule of repetition was governed by the size of the partitions in the learning box. These were 1, 2, 5, 8 and 14 cm. Only when a partition became full was the learner to review some of the cards it contained, moving them forward or back depending on whether they remembered them.
There is a wide range of software (including open source and online services) available for creating and using virtual flashcards as an aid to learning.
Physical flashcards are two-sided; in some contexts one wishes to correctly produce the opposite side upon being presented with either side, such as in foreign language vocabulary; in other contexts one is content to go in only one direction, such as in producing a poem given its title or incipit (opening). For physical flashcards, one may either use a single card, flipping it according to the direction, or two parallel decks, such as one English-Japanese and one Japanese-English. They have a number of uses and can be simple or elaborate depending on the user.

Physical flashcards are necessarily two-sided. A variant, found in electronic flashcards, is what is known as a three-sided card. [4] This is a particular kind of asymmetric two-sided card; abstractly, such a card has three fields, Q, A, A*, where Q & A are reversed on flipping, but A* is always in the answer – the two "sides" are thus Q/A,A* and A/Q,A*. Concretely, these are most used for learning foreign vocabulary where the foreign pronunciation is not transparent from the foreign writing – in this case the Question is the native word, the Answer is the foreign word (written), and the pronunciation is always part of the answer (Answer*). This is particularly the case for Chinese characters, as in Chinese hanzi and Japanese kanji, but can also be used for other non-phonetic spellings, including English as a second language.
The purpose of three-sided cards is to provide the benefits of two-sided cards – ease of authoring (enter data once to create two cards), synchronized updates (changes to one are reflected in the other), and spacing between opposite sides (so opposite sides of the same card are not tested too close together) – without the card needing to be symmetric.
One can generalize this principle to an arbitrary number of data fields associated with a single record, with each field representing a different aspect of a fact or bundle of facts.
Paper flashcards have been used since at least the 19th century, with Reading Disentangled (1834), a set of phonics flashcards by English educator Favell Lee Mortimer being credited by some as the first flashcards. [5] Previously, a single-sided hornbook had been used for early literacy education.
The Leitner system for scheduling flashcards was introduced by German scientific journalist Sebastian Leitner in the 1970s, specifically his 1972 So lernt man lernen. Der Weg zum Erfolg (How to learn to learn), [6] while the SuperMemo program and algorithm (specifically the SM-2 algorithm, which is the most popular in other programs) was introduced on December 13, 1987, by Polish researcher Piotr Woźniak. [7]
Incremental reading is a software-assisted method for learning and retaining information from reading, which involves the creation of flashcards out of electronic articles. "Incremental reading" means "reading in portions". Instead of a linear reading of articles one at a time, the method works by keeping a large list of electronic articles or books and reading parts of several articles in each session. The user prioritizes articles in the reading list. During reading, key points of articles are broken up into flashcards, which are then learned and reviewed over an extended period with the help of a spaced repetition algorithm.
Spaced repetition is an evidence-based learning technique that is usually performed with flashcards. Newly introduced and more difficult flashcards are shown more frequently, while older and less difficult flashcards are shown less frequently in order to exploit the psychological spacing effect. The use of spaced repetition has been proven to increase the rate of learning.
SuperMemo is a learning method and software package developed by SuperMemo World and SuperMemo R&D with Piotr Woźniak in Poland from 1985 to the present. It is based on research into long-term memory, and is a practical application of the spaced repetition learning method that has been proposed for efficient instruction by a number of psychologists as early as in the 1930s.
A vocabulary is a set of words, typically the set in a language or the set known to an individual. The word vocabulary originated from the Latin vocabulum, meaning "a word, name". It forms an essential component of language and communication, helping convey thoughts, ideas, emotions, and information. Vocabulary can be oral, written, or signed and can be categorized into two main types: active vocabulary and passive vocabulary. An individual's vocabulary continually evolves through various methods, including direct instruction, independent reading, and natural language exposure, but it can also shrink due to forgetting, trauma, or disease. Furthermore, vocabulary is a significant focus of study across various disciplines, like linguistics, education, psychology, and artificial intelligence. Vocabulary is not limited to single words; it also encompasses multi-word units known as collocations, idioms, and other types of phraseology. Acquiring an adequate vocabulary is one of the largest challenges in learning a second language.
Rote learning is a memorization technique based on repetition. The method rests on the premise that the recall of repeated material becomes faster the more one repeats it. Some of the alternatives to rote learning include meaningful learning, associative learning, spaced repetition and active learning.
Linkword is a mnemonic system promoted by Michael Gruneberg since at least the early 1980s for learning languages based on the similarity of the sounds of words. The process involves creating an easily visualized scene that will link the words together. One example is the Russian word for cow : think and visualize "I ran my car over a cow."
Pythagorean Method of Memorization (PYMOM), also known as Triangular Movement Cycle (TMC), is a game-based, educational methodology or associative-learning technique that primarily uses corresponding information, such as terms and definitions on opposing sides, displayed on cue cards, to exploit psychological retention of information for academic study and language acquisition. PYMOM is named such because of the shape the cue-cards form during the progression of the game, a right-angled or Pythagorean triangle.
Study skills or study strategies are approaches applied to learning. Study skills are an array of skills which tackle the process of organizing and taking in new information, retaining information, or dealing with assessments. They are discrete techniques that can be learned, usually in a short time, and applied to all or most fields of study. More broadly, any skill which boosts a person's ability to study, retain and recall information which assists in and passing exams can be termed a study skill, and this could include time management and motivational techniques.

Distributed practice is a learning strategy, where practice is broken up into a number of short sessions over a longer period of time. Humans and other animals learn items in a list more effectively when they are studied in several sessions spread out over a long period of time, rather than studied repeatedly in a short period of time, a phenomenon called the spacing effect. The opposite, massed practice, consists of fewer, longer training sessions and is generally a less effective method of learning. For example, when studying for an exam, dispersing your studying more frequently over a larger period of time will result in more effective learning than intense study the night before.
