【正文】 rity of the trend, you probable haven’t heard of the University of Phoenix. It grants degrees entirely on the basis of online instruction. It enrolls 90,000 students, a statistic (數(shù)據(jù)) used to support its claim to be the largest private university in the country.While the kinds of instruction offered in these programs will differ, DL usually indicates a course in which the instructors post syllabi (課程大綱), reading assignments, and schedules on Websites, and students send in their assignments by . Generally speaking, facetoface munication with an instructor is minimized or eliminated altogether.The attraction for students might at first seem obvious. Primarily, there’s the convenience promised by courses on the net: you can do the work, as they say, in your pajamas (睡衣), but figures indicate that the reduced effort results in a reduced mitment to the course. While dropout (輟學(xué)) rates for all freshmen at American universities is around 20 percent, the rate for online students is 35 percent. Students themselves seem to understand the weakness inherent (內(nèi)在的) in the setup. In a survey conducted for eCornell, the DL division of Cornell University, less than a third of the respondents expected the quality of the online course to be as good as the classroom course.Clearly, from the school’s perspective, there’s a lot of money to be saved. Although some of the more ambitious programs require new investments in servers and networks to support collaborative software, most DL courses can run on existing or minimally upgraded (升級) systems. The more students who enroll in a course but don’t e to campus, the more the school saves on keeping the lights on in the classrooms, paying doorkeepers, and maintaining parking lots, and, while there’s evidence that instructors must work harder to run a DL course for a variety of reasons, they won’t be paid any more, and might well be paid less.76.

Students’ responsibility for learning80. There is considerable variety in university classrooms in the United States. Because of diverse teaching methods and nonstandardized curricula (課程), no two courses are the same. Undergraduate courses are considerable different from graduate courses. The classroom atmosphere in expensive, private universities may differ from that in munity colleges which are free and open to everyone. 81. Participation (參與) in the classroom is not only accepted but also expected of the student in many courses. Some professors base part of the final grade on the student’s oral participation. Although there are formal lectures during which the student has a passive role (., listening and taking notes), many courses are organized around classroom discussions, student questions, and informal lectures.s latest offering scored most for appearance. Sounds clear, but there is slight machine noise. The big control buttons are a great improvement on some of the plicated little controls on other taperecorders. Doesn39。 London, the British Museum. Florida International University (FIU) in Miami also shows art for people to see. And it does so without a building, or even a wall for its drawings and paintings.FIU has opened what it says is the first puter art museum in the United States. You don’t have to visit the University to see the art. You just need a puter linked to a telephone. You can call the telephone number of a university puter and connect your own puter to it. All of the art is stored in the school puter. It is puter art, produced electronically by artists on their own puters. In only a few minutes, your puter can receive and copy all the pictures and drawings.Robert Shostak is director of the new puter museum. He says he started the museum because puter artists had no plac
