Teachers began to change the way they used computers to teach language. Computer programs were developed that accepted a variety of responses and did not judge the students when they made mistakes.
Some computer games were developed to teach language. Students were able to mae choices and interact with the computer in a way that gave the student more control. Computer is used as stimulus.
The PC was introduced in the late 1970's, computers could now be used as a tool, or as an outlet for the creative energy of students and were used to stimulate writing, discussions and critical thinking. Computers included spelling and grammar checkers, desk top publishing programs and presentation software.

The technology advanced in two important ways: multimedia and de world wide web.
CD ROMS made multimedia programs possible, programs that include text, images, animations, videos and sounds. The student has more freedom to explore and learn according to his/her own needs and interests, and recieve input in a variety of modes.
The early internet was used for military and academic research. (videos were not very practical because they were so slow)
Hypermedia can be used within an educational program. (students simply need to click on the link to bring the new files to the screen)
Teachers need to remember that computers are machines, computers are helpful to educators , but they cannot, and should not, be used to replace a human teacher. (computers are an important tool for educators, but technology by itself does not make an effective lesson)
