Since 1984, CALL materials have been used on a regular basis in the German Department at the University of Aberdeen in integrated language courses, in order to practise and consolidate the material taught in face-to-face contact classes. CALL work essentially forms a backup to the taught part of the course. What the students are taught one week, they practise in their CALL class the following week, and additionally have the opportunity to work on further exercises on a private-study basis. Within the field of language learning, our experience suggests that the computer can be above all a superb tool for revision and consolidation. With the development and use of hypertext materials, there is more than just the possibility that it can now become even more effective than hitherto.
