Khan Academy is a globally recognized non-profit education platform founded by Salman Khan in 2006. Its mission is to provide free, high-quality educational resources to students around the world, helping them access support and guidance in their learning. Through its website and mobile app, Khan Academy offers a vast amount of instructional videos, exercises, and course content covering multiple subjects from primary school to university.
The Origin and Development of Khan Academy
The founder of Khan Academy is Salman Khan, an educator and entrepreneur with degrees from MIT and Harvard University. Khan Academy originated from a chance encounter: Salman Khan initially helped his cousin learn math through video tutorials. Over time, these tutorials gained widespread attention online, and more and more students and parents began requesting Khan to create more instructional videos. Therefore, Khan decided to upload his videos to YouTube, making them available to a wider audience for free.
As the videos spread, Khan gradually realized the potential of this online education model. In 2006, he officially founded Khan Academy and began systematically producing and releasing instructional videos. Khan Academy's development has received support from many well-known institutions and individuals, including the Bill Gates Foundation and Google. This support has enabled Khan Academy to continuously expand its teaching content and technology platform, becoming one of the world's most popular online education platforms.
