Stanford Online
Stanford Online is an educational initiative launched by Stanford University which offers a variety of professional education opportunities. As a part of Stanford Online, Stanford University created an open access OpenEdX platform which offered a variety of massive open online courses (MOOCs) in 2013, but that site is no longer accessible. Online classes previously offered on that platform can now be accessed on an updated platform known as edx that offers a wide range of online courses covering many topics. Some of the online classes offered by Stanford Online on this platform are available free of charge. Classes can be accessed from anywhere around the world.
