Khan Academy

Khan Academy is an American non-profit educational organization created in 2006 by Sal Khan. Its goal is to create a set of online tools that help educate students. The organization produces short video lessons. Its website also includes supplementary practice exercises and materials for educators. It has produced over 10,000 video lessons teaching a wide spectrum of academic subjects, including mathematics, sciences, literature, history, and computer science. All resources are available for free to users of the website and application.

History
Starting in 2004, Salman "Sal" Khan began tutoring one of his cousins in mathematics on the Internet using a service called Yahoo! Doodle Images. 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. 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.

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) Khan Lab School, a school founded by Sal Khan and associated with Khan Academy, opened on September 15, 2014, in Mountain View, California.

Funding
Khan Academy is a 501(c)(3) non-profit organization, mostly funded by donations from philanthropic organizations. 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.

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

Content
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, and teaching tools. The material can also be accessed through mobile applications. 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.

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 they relate to the material being taught. Furthermore, throughout the lessons, users can earn badges and energy points, which can be displayed on their profiles. Non-profit groups have distributed offline versions of the videos to rural areas in Asia, Latin America, and Africa. 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. It also provides online courses for preparing for standardized tests, including the SAT, AP Chemistry, Praxis Core and MCAT and released LSAT preparation lessons in 2018. They also have a collaboration with independent chemists, which are mentioned in their, "Meet the chemistry professional". Khan Academy has also supported Code.org's Hour of Code, providing coding lessons on its website.

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

Khanmigo
Khanmigo is a chatbot powered by GPT-4 technology, designed to assist users with mathematics, science, humanities, and coding inquiries, as well as aiding in learning these subjects. It incorporates the large language model of OpenAI. Khan Academy introduced Khanmigo on March 14, 2023. Users can have access for $4 per month. Users who want to register must be over 18.

Language availability
Khan Academy videos have been translated into several languages, with nearly 20,000 subtitle translations available. These translations are mainly volunteer-driven with help from international partnerships. The Khan Academy platform is fully available 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 available in 28 other languages.

Official SAT preparation
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 average score increase.

Pixar in a Box
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.

Official Test Preparation
Khan Academy also provides free test preps for PSAT/NMSQT, LSAT, Praxis Core, and MCAT.

Khan Academy Kids
In 2018, Khan Academy created an application called Khan Academy Kids. It is used by two to eight-year-old children to learn basic skills (primarily mathematics and language arts) before progressing to grade school.

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

Criticism
Khan Academy has been criticized because its creator, Sal Khan, lacks a formal background or qualifications in pedagogy. Statements made in certain mathematics and physics videos have been questioned for their technical accuracy. 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.

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." 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.
