Salman khan, a Bangladeshi-American who was highly praised by Bill Gates as a "network teacher", became a "network teacher" by accident. In 2004, one of Khan's relatives, Nadia, met a math problem. She asked her cousin, a "math genius", for help. Through Yahoo! S chat software, interactive wordpad and telephone, Khan helped her answer all the questions. In order to make her understand, he tried to make it easy to understand. Soon, his nephew, nephew and niece also came to ask for advice. Khan was too busy at that time. He simply made his math tutoring materials into videos and put them on YouTube for more people to share.
Nowadays, in American education, Khan's position is like Moses in religious circles. He founded an educational non-profit organization relying on Khan Academy, the main purpose of which is to use online movies to teach for free. There are more than 2,000 teaching films covering mathematics, history, finance, physics, chemistry, biology and astronomy. The mission of this organization is to speed up the learning of students of all ages. Khan's career has been recognized by more and more society. The material support that followed made this free website more active. On the one hand, due to the extremely high number of teaching videos, Khan can get about $2,000 (about 6.5438+0.3 million yuan) of advertising share from YouTube every month. On the other hand, many students send him money spontaneously, ranging from tens of dollars to 10 thousand dollars. It is reported that Dole, a famous American venture capitalist, and his wife donated $654.38 million+to him. Khan used the money to translate the existing videos into Spanish, French, Russian, Chinese and other languages 10, and hired some assistants.
