One of the goals of American education officials is to have all public schools connected to the Internet computer system and have computer for all students. Government studies show that in 1994 only thirty-five percent of American public schools were connected to the Internet. Last year, that number reached eighty-nine percent.
Virginia Polytechnic Institute of State University is a large university in the southern state of Virginia. Officials at Virginia Tech say computers are very important to a student’s education. All students at Virginia Tech have been required to have a computer since 1998.
Each student’s living area at Virginia Tech has the necessary wires to link a computer to the Internet. The students can send and receive electronic mail, use the World Wide Web part of the Internet and link with other universities, all without leaving their room. They can also use their computers to send electronics copies of their schoolwork to their teachers. And they can search for books in the school’s huge library.
Most major American universities and colleges strongly urge or require new students to have a computer. Most colleges and universities also have large rooms where students can use computers for class work.
American high schools also have computers. Many have their own areas on the World Wide Web. If you have a computer you can learn about Fremont Union High School in Sunnyvale, California, for example. Its Web site provides information about the school, the teachers and their electronic mail addresses. It also lists student events and organizations.
Young children also use computer in school. Smoketree Elementary School in Lake Havasu, Arizona has given us a good example. The school also has a World Wide Web site. It tells about the school and the teachers and has an area for young children. These young children use computer in school to learn numbers and letters.
