Quizlet is a mobile and web-based study application that allows students to study information via learning tools and games. It is currently used by 2-in-3 high school students and 1-in-3 college students in the United States.[3] It was created by Andrew Sutherland in October 2005 and released to the public in January 2007.[4] Quizlet trains students via flashcards and various games and tests. As of April 30, 2018, Quizlet has over 200 million user-generated flashcard sets and more than 30 million active users.[5] It now ranks among the top 50 websites in the U.S.[6] In 2016, Quizlet was recognized by SimilarWeb as the fastest growing US Education site in 2015.[7]

History

Quizlet began as an idea conceptualized by Sutherland to memorize 111 animal names for his French class.[8][9] To aid in memorizing the names, he began writing a program to help him study.[10] These first lines of code were deleted and then rewritten over a course of 420 days. In October 2005, Quizlet was released to the public.[11]

Until 2011, Quizlet shared staff and financial resources with the Collectors Weekly web site.[12] In 2015, Quizlet announced raising $12 million from Union Square Ventures, Costanoa Venture Capital, Altos Ventures and Owl Ventures to expand its digital study tools and grow internationally.[6]

In 2011, Quizlet added the ability to listen to content using text-to-speech.[13] In August 2012, Quizlet released an app for the iPhone and iPad and shortly afterward released an app for Android devices.[12]

On April 29, 2015, Quizlet enabled HTTPS on their site.[14].

On August 10, 2016, Quizlet introduced a revamp to their website with a new design interface, along with a new logo and homepage. Their mobile apps for iOS and Android also received a design interface update.[15]

On August 23, 2017, Quizlet introduced a new diagramming feature[16] to help learners with subjects heavy on visuals like geography, vocabulary, anatomy, and architecture.

On February 6, 2018, Quizlet announced that it had raised an additional $20 million in Series B funding,[17] led by Icon Ventures.

Study modes and games

As a memorization tool, Quizlet lets registered users create sets of terms and definition customized for their own needs.[18] These sets of terms can then be studied under several study modes.[19][20]

Flash Cards
This mode is similar to paper flash cards. In it, users are shown a "card" for each term. Users can click to flip over the card or use their arrow keys or space bar, and see the definition for that term.[21] The user has the option for the face of the card to be a picture, writing, or both if it is desired.
Gravity
In this study mode, definitions scroll vertically down the screen in the shape of asteroids. The user must type the term that goes with the definition before it reaches the bottom of the screen. It is one of the 'Play' study modes.[22] Gravity was adapted from a previous game, Space Race. The user can pick the level of difficulty and game type.
Learn
In this study mode, users are shown a term or definition and must type the term or definition that goes with what is shown. After entering their answer, users see if their answer was correct or not, and can choose to override the automatic grading and count their answer as right if needed.
Long-Term Learning
In this study mode, users are given a recommended study set based on whether or not they answer study set questions correctly. Repetition of terms answered incorrectly increases in frequency and a dashboard shows learning progress over time. The mode uses spaced repetition concepts to focus on longer-term retention and subject mastery versus shorter-term memorization.[23]
Speller
In this mode, the term is read out loud and users must type in the term with the correct spelling. If the user gets every answer correct, they are rewarded with a video of a monster truck doing a jump, wheelie, and a flip. [21]
Match
In this study mode, users are presented with a grid with terms scattered around it. Users drag terms on top of their associated definitions to remove them from the grid and try to clear the grid in the fastest time possible. Micro-match is a related matching game geared towards mobile devices and devices with small screens. Users may access the Micromatch mode on non-mobile devices by manually editing the URL in Match mode to use "micromatch" instead of "match".[21] Match was previously attributed as "Scatter". Though the name of the study mode changed, the game itself did not.
Live
In this study mode, a Quizlet user with a Teacher upgrade (usually a teacher) breaks their class up into teams of however number of teams they want. The teacher chooses whether to start with a definition or term. Each team will have to choose the correct term/definition to win, with the team that has the most points winning. If the teacher decides to shuffle the teams, the groups are randomly put into new teams. This game works by choosing a set of flashcards and putting these flashcards into a format which works for the game.

API

Quizlet provides an API that allows others to access Quizlet data. Available functions include uploading and downloading flashcards, modifying users' flashcards, and finding definitions created by Quizlet users.[24]
