These 1 a are online, free of charge, and open to anyone in the world who has a laptop and an Internet connection. Moreover, they are mainly 2 by elite ( 精英 ) universities like Stanford, Berkeley, Harvard and Columbia. Though MOOCs are not offered for credit and degree, many students enroll in ( 选课 ) the courses for real skills or knowledge which they can put to some 3 use. The format seems superior to the 4 school class. The average quality of the lecturer is much higher, because students do not have to stick with an ordinary 5 . Besides, students can go at their own learning speed, which they cannot do in a live lecture. And, of great importance, they do not have to travel anywhere to 6 an online lecture. One can obtain a first-class American college education wherever he or she lives and however little money he or she has. There is a problem of asking 7 of the lecturer in a class of ten thousand students, but some MOOCs have solved it by 8 students to post questions 9 for a vote, and only the most popular questions are put to the lecturer. Students in MOOCs are very clever, have work experience, and in many cases, have already developed a set 10 core ( 核心 ) competences. Moreover, they also offer unique international perspectives ( 视野 ) that would be the envy of any school classroom.
