edX

edX  is a nonprofit enterprise which provides an open-source online learning platform for highest quality education. It is founded by Massachusetts Institute of Technology (MIT) and Harvard University. Its interactive free of cost courses are available to public on various topics including biology, business, chemistry, computer science, economics, finance, electronics, engineering, food and nutrition, history, humanities, law, literature, math, medicine, music, philosophy, physics, science, statistics and more.

Unlike  standard model of online education which depends  only on video content, edX offers an interactive experience for students. Students can participate in  quizzes to receive instant feedback, discuss the subject on course boards and work in online laboratories. Its technology is open-source, so the platform will be continuously improved by worldwide collaborators. edX offers self-paced learning and discussion groups. Certificate of achievement can be earned after successful completion of course for a modest fee.

The edX platform also serves as a laboratory from which data is gathered to better understand how students learn. 

edX updates

edX is going to expand its horizon by  offering courses for high school students. This will help to address a “readiness gap” that leaves a significant number of high school students unprepared for college studies.

edX is  also launching courses for employers and employees in the professional sphere. It will charge for professional education courses starting next year. The subjects would include leadership, IT, business, education, engineering, energy, medicine and big data.
