Khan Academy is an American educational nonprofit[3] created in 2008 by Sal Khan.[1] Its goal is to create a set of online tools that help educate students.[4] The organization produces short video lessons.[5] Its website also includes supplementary practice exercises and materials for educators. It has produced over 10,000 video lessons[6] teaching a wide spectrum of academic subjects, including mathematics, sciences, literature, history, and computer science. All resources are ailable free to users of the website and application.

History[edit] Sal Khan presenting during TED 2011

Starting in 2004,[7] Salman "Sal" Khan began tutoring one of his cousins in mathematics on the Internet using a service called Yahoo! Doodle Images.[8] After a while, Khan's other cousins began to use his tutoring service. Due to the demand, Khan decided to make his videos watchable on the Internet, so he published his content on YouTube.[9] Later, he used a drawing application called SmoothDraw, and now uses a Wacom tablet to draw using ArtRage. The video tutorials were recorded on his computer.[10]

Reading positive responses in USA Today prompted Khan to incorporate Khan Academy in 2008 and quit his job the same year to focus full-time on creating educational tutorials (then released under the name Khan Academy).[11] Khan Lab School, a school founded by Sal Khan and associated with Khan Academy, opened on September 15, 2014, in Mountain View, California.[12]

May-Li Khoe served as Vice President of Design at Khan Academy from 2014 to 2019, contributing to the organization's user experience and design strategy during her tenure.[13]

Funding[edit]

Khan Academy is a 501(c)(3) non-profit organization, mostly funded by donations from philanthropic organizations.[14] On its IRS form 990, the organization reported $31 million in revenues in 2018 and $28 million in 2019, including $839,000 in 2019 compensation for Khan as CEO.[15]

In 2010, Google donated $2 million for creating new courses and translating content into other languages, as part of their Project 10100 program.[16] In 2013, Carlos Slim from the Luis Alcazar Foundation in Mexico, made a donation for creating Spanish versions of videos.[17] In 2015, AT&T contributed $2.25 million to Khan Academy for mobile versions of the content accessible through apps.[18] The Bill & Melinda Gates Foundation has donated $1.5 million to Khan Academy.[19] On January 11, 2021, Elon Musk donated $5 million through his Musk Foundation.[20]

Content[edit] The narrator writes to an electronic blackboard during a recorded lecture.

Khan Academy offers classes with educational videos hosted on YouTube. The website is meant to be used as a supplement to the videos, because it includes other features such as progress tracking, practice exercises,[21] and teaching tools.[22] The material can also be accessed through mobile applications.[23] The videos enable students to acquire knowledge at their own learning speed according to the concept of mastery learning. They are therefore used by teachers to teach according to the principle of Flipped Classroom.[24]

The videos display a recording of drawings on an electronic blackboard, which are similar to the style of a teacher giving a lecture. The narrator describes each drawing and how the drawings relate to the material being taught.[25][26] Furthermore, throughout the lessons, users can earn badges and energy points, which can be displayed on their profiles. Non-profit groups he distributed offline versions of the videos to rural areas in Asia, Latin America, and Africa.[27][28][29] Videos range from all subjects covered in school and for all grades from kindergarten up through high school. The Khan Academy website also hosts content from educational YouTube channels and organizations such as Crash Course and the Museum of Modern Art.[30] It also provides online courses for preparing for standardized tests, including the SAT, AP Chemistry, Praxis Core and MCAT[31] and released LSAT preparation lessons in 2018.[32] It also has a collaboration with independent chemists, which are mentioned in "Meet the chemistry professional". Khan Academy has also supported Code.org's Hour of Code, providing coding lessons on its website.[33]

In July 2017, Khan Academy became the official practice partner for the College Board's Advanced Placement.[34]

Khanmigo[edit]

Khanmigo is a chatbot designed to assist users with mathematics, science, humanities, and coding inquiries, as well as aiding in learning these subjects. Khan Academy introduced Khanmigo on March 14, 2023. It was initially based on GPT-4, a large language model by OpenAI.[35][36] Users can he access[37] for $4 per month. Users who want to register must be over 18. The pilot provided access to approximately 65,000 students across 53 school districts. In November 2023, Khanmingo Writing Coach was introduced to provide essay-writing support for students and analytical insights for teachers.[38][39] In August 2024, Khanmigo for Teachers, a set of free generative AI tools for educators, was announced in partnership with Microsoft.[40] In December 2024, Khanmigo was featured on an episode of 60 Minutes with host Anderson Cooper, who tried the Writing Coach on one of his essays from middle school.[41]

Language ailability[edit]

Khan Academy videos he been translated into several languages, with nearly 20,000 subtitle translations ailable. These translations are mainly volunteer-driven with help from international partnerships.[42][43] The Khan Academy platform is fully ailable in English (en), Bangla (bn), Bulgarian (bg), Chinese (zh), French (fr), German (de), Georgian (ka), Norwegian (nb), Polish (pl) Portuguese (pt), Spanish (es), Serbian (sr), Turkish (tr) and Uzbek (uz), and partially[44] ailable in 28 other languages.[45]

Official SAT preparation[edit]

Since 2015, Khan Academy has been one of the official SAT preparation websites. According to reports, studying for the SAT for at least 20 hours at Khan Academy is associated with a 115-point erage score increase.[46]

Pixar in a Box[edit]

In 2015, Khan Academy teamed up with Pixar to create a new course named Pixar in a Box, which teaches how skills learned in school help the creators at Pixar.[47]

Official Test Preparation[edit]

Khan Academy also provides free test preps for PSAT/NMSQT,[48] LSAT, Praxis Core, and MCAT.

Khan Academy Kids[edit]

In 2018, Khan Academy launched an application called Khan Academy Kids for children aged two to seven to learn basic maths, reading and social skills.[49][50]

Teachers[edit]

Teachers can set up a classroom within Khan Academy. This classroom allows teachers to assign courses within Khan Academy's database to their students.[51] Teachers can also track their student's progress as they work through the assigned tutorials.

Criticism[edit]

Khan Academy has been criticized because its creator, Sal Khan, lacks a formal pedagogical background.[52] Statements made in certain mathematics and physics videos he been questioned for their technical accuracy.[53] In response to these criticisms, the organization has corrected errors in its videos, expanded its faculty, and formed a network of over 200 content experts.[53]

In an interview from January 2016, Khan defended the value of Khan Academy online lectures while acknowledging their limitations: "I think they're valuable, but I'd never say they somehow constitute a complete education."[12] Khan Academy positions itself as a supplement to in-class learning, with the ability to improve the effectiveness of teachers by freeing them from traditional lectures and giving them more time to tend to individual students' needs.[54][19]

In February 2024, a Wall Street Journal reporter tested the math tutoring capabilities of Khan Academy's AI chatbot Khanmigo and found that it made basic calculation errors.[55]

Recognition[edit] In 2012, Khan Academy won a Webby Award in the category Websites and Mobile Sites, Education.[56] In 2016, Khan Academy won a Shorty Award for Best in Education.[57] See also[edit] FutureLearn Pluralsight EdX Coursera Udemy Udacity LinkedIn Learning References[edit] ^ a b "What is the history of Khan Academy?".
