Sample answer

Students would need to be registered with bellenglish.com before they could access the exercise.  In order to use these exercises your computers need Shockwave (this is already installed on many computers in schools and if not can be easily downloaded free).  You would need either a computer each or one between two and a pair of headphones each.  Other than basic knowledge about clicking with the mouse the students wouldn't need any special computer skills.

There's a wide range of exercises for students, an assessment test, vocabulary exercises such as Label the Picture, a language learning game, and a lot of exercises at all levels working on grammar, reading, writing, listening and vocabulary.  In addition there's an FCE course, a business English course on Telephoning, a chat room, bulletin board, e-postcards.  It would be useful to give the address of this site to your students who have computer access.  There are lots of exercises that they could do on their own and perhaps join discussions on the bulletin board too.
