Computerization has changed high school education in many ways. In early 1980s

only 20% of high school teachers in the US used computers. However, since then high

schools in the US have computerized rapidly. In 1987, school acquired about 1.5 million

computers with 95% of the schools having at least one computer. At school, teachers can use

a computer to bring texts, sound and pictures into a classroom. With a computer, they can

readily attract and retain students’ attention. Computers can also speed up the teaching

process and make difficult- to- explain ideas straight forward. This means that teachers can

spend more time answering students’ questions and catering for other needs. Computer

software can shorten the learning process by illustrating real world applications of abstract

theories.
