Recently, computers have become a very helpful teaching aid in the classroom. More schools provide their learners with opportunities to use computer technology (the Internet in particular) to learn new and interesting information. I think it's useful not only for the teaching of subject like physics, maths, chemistry, biology and geography, but also for practising foreign languages, especially English.
First of all, most of the material on the Internet is in English. Students can see examples of real-life communication, find out about the use of the grammar and vocabulary they are learning in their lessons and find all sorts of online publications in a quick and convenient way.
Secondly, students can expand their horizons by getting to know a lot about people and far away places they will never be able to visit. They can read texts on the websites, play videos, solve quizzes and join discussion groups. These are only some of the options available to students. Additionally, they can become penfriends or rather e-mail friends and exchange personal information over the Internet.
The Internet gives teachers many ideas for making their lessons attractive. It has popular dictionary sites, pages with information about English-speaking countries, lesson plans and attractive collections of exercises written by experienced teachers from various parts of the world.
It is not very difficult to make students use the computers for learning purposes. I believe most students would love the chance of having at least one lesson a week to surf through the Internet.
