Massive Open Online Courses, called MOOCs, are changing how people learn in many places. For years,

18、people could receive study materials from colleges or universities and take part in online classes. But such classes were not designed for many thousands of students at one time, as MOOCs are. So todays topic is, how MOOCs change our education. Course materials provided by MOOCs can serve both those

19、 studying far away from school and those attending classes in person. Anyone with a computer and an online connection can sign up for a MOOC. Students do not have to pass entrance exams. They also do not need to have studied the subject before. One professor praised MOOCs because they let people who

20、 could not attend a traditional college to continue their education. He asked, Who knows where the next Albert Einstein will come from? The spread of Internet learning for huge numbers of people is leading some colleges to join the movement. Major universities like Stanford in California and Harvard

They usually have videos, home-work, weekly tests, a final examination and a rating in the class. Stanford University computer s

23、cientist, Daphne Koller, says that before long, people may wonder why college students ever filled a room to hear a lecture.

24、. Today, MOOCs have more than one million students. Will many of these students do all of their college work by computer? If so, they would enter the professional world with course completion documents instead of a degree. For years, a degree has been the sign to employers that students have complet

25、ed the requirements for a college education. But today, employers may be more than willing to offer work to a student with an excellent record in MOOCs without a college degree. That is especially true at technology companies. He also says computer-based distance learning and asynchronous learning w

26、ill be part of the future university. Asynchronous learning lets students do the course work at any time. The professor predicts that those methods will be used with individual tutoring, life experience, independent study and lectures. But the investment service is warning that smaller, less well-kn

27、own colleges may suffer because of MOOCs. It says students may want to receive certificates from major universities instead of attending a local junior college that provides traditional credits. So what is your comment on the future of MOOCs? Will MOOCs replace the traditional colleges and universit

37、 got a minute? W: Sure. So you think we can get a presentation out of this article? M: Im sure we can.

38、 million! M: Exactly. And they say that the manufacturers of these cans exercise as much attention and precision in producing them as aircraft manufacturers do when they make the wing of an aircraft! W: Really!

43、the can. W: Got that. I think we should label the lid itself and say that it constitutes twenty-five percent of the total weight. M: Twenty-five percent. so its stronger than the body of the can. W: So to save money, manufacturers make it smaller than the rest of the can! M: Didnt know that, either.
