A School That Can Educate Us All
Christos Porios，16，lives in a small Greek city．"My mother's a teacher and my father's a mechanic，"he explains，adding that neither is knowledgeable about computers-especially compared with him．（67）C
Porios was taking a free class in machine learning offered by Andrew Ng，a professor at Stanford University，over an online platform Ng developed with his colleagues．Drawing on what he learned，Porios was able to participate in the International Space Apps Challenge，a virtual hackathon （编程马拉松） using data from NASA and other government agencies．
If one teenager in one small city can become a genius hacker through an online course，does it mean the world has changed？We have been hearing about the potential of online education for decades．
（68）A A number of online education platforms have appeared，featuring professors from top universities offering free courses．
（69）F Ng was amazed．"It would take me 250 years to teach this many people at Stanford，"he says．And so，just one month into the course，Ng and his Stanford colleague，Daphne Koller，decided to leave their faculty posts （教职） and dive into online teaching full-time．In April，they launched their company，Coursera，with a $16 million round of venture funding．So far，it has managed to team up with 35colleges in nine countries．
To Ng and Koller，Coursera's mission is simple and yet grand．That is to teach millions of people around the world for free，while also transforming higher education．
According to Ng，the world's top 20universities enroll only about 200，000 students．There are million more who could participate in classwork at the higher level，but most of them are far from any of the leading universities．（70）E
Koller says Coursera's total registration has hit 15 million．Porios，the young Greek，is only one of those registrants．His hope is to study in Germany or England someday．He is even toying with the idea of taking classes at MIT or Stanford-but this time in person．
| A．Finally，it has taken a giant leap forward． B．All of the factors pushing online education toward the mainstream of higher education are now crashing together． C．Over the past few years，he has been teaching himself programming． D．In other words，Coursera's approach is a long way from a simple online video lecture． E．Yet the most exciting promise of their company and the like is the role they might play in improving education for the poor around the world． F．Ng's course in machine learning attracted 104，000 enrollees around the world． |
