     Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and

hotels. These laptops connect people to their workplace. In the United States today, laptops also connect

students to their classrooms.

     Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork

anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The

laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students with

laptops will also have access to the Internet. In addition, they will be able to use e-mail to "speak" with their

teachers, their classmates, and their families. However, the most important part of the laptop program is that

students will be able to use computers without going to computer labs. They can work with it at home, in a

fast-food restaurant or under the trees-anywhere at all!

     Because of the many changes in computer technology, laptop use in higher education, such as colleges

and universities, is workable. As laptops become more powerful, they become more similar to desktop

computers. In addition, the portable computers can connect students to not only the Internet, but also libraries

and other resources. State higher-education officials are studying how laptops can help students. State

officials are also testing laptop programs at other universities, too.

     At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers

to use computers in their lessons. As one Westlake teacher said, "Here we are in the middle of Virginia and

we're giving students a window on the world.They can see everything and do everything."
