• Online learning is also called distance education. Many American colleges and universities have been offering it for years.

  One example is New York University in Manhattan. The School of Continuing and Professional Studies began online classes in nineteen ninety-two. Its Virtual College has taught more than ten thousand students from across the United States and other countries. Last year, the School of Continuing and Professional Studies launched NYU Online. It offers NYU's first online programs to earn a bachelor's degree. Programs are offered in three areas: leadership and management, information systems management and social sciences. University officials say classes are highly interactive, where students communicate with each other and their teachers. Some classes require students to all log in at the same time so they can attend live lectures by a professor. Students can also ask questions and work together on team projects. The university says classes are taught by NYU professors who have been trained in online teaching. International students must take two admission tests before they can be accepted into the program. These are the SAT and the TOEFL. We will discuss these tests later in our series. The cost to attend NYU Online depends on how many classes a student takes. It can cost as much as fifteen thousand dollars a year. NYU offers no financial aid for international students in this program. You can get more details at nyu.edu. 1. When did New York University start its online classes？ A. In 1990 B. In 1998. C. In 1992. D. In 1982. 2. Which of the following is NOT included in the online programs offering a BA degree？ A. Information Systems Management. B. Finance and Economy. C. Leadership and Management. D. Social Sciences. 3. What can the students do in the online learning programs？ A. Communicate with each other and the teacher. B. Attend classes and lectures together. C. Ask questions and work together on team projects. D. Students are taught by NYU professors in the classroom. 4. International students can be accepted into the program after ________ . A. they take the SAT and the TOFEL B. they go to New York University C. they apply and log in D. two years in the United States 5. How much does the online learning program cost per year？ A. $15,000. B. $1,500. C. It depends. D. $5,000.

• Can online education ever be education of the very best sort？ Not long ago I watched an online course. The instructor was intelligent and learned. But the course wasn t great and could never have been. There were students on hand, but the class seemed addressed to no one in particular. There was nothing you could get from that course that you couldn t get from a good book on the same subject. A truly memorable college class is a cooperation between teacher and students. It s a one-time-only event. Learning at its best is collective work. In real courses the students and teachers come together and create a vital atmosphere of learning. I don t think an Internet course ever will.
