Trained and experienced ELT teachers sometimes report feeling deskilled when they first teach EAP. They may be unaware that the criteria they normally apply to identify needs or evaluate lessons are not necessarily the same in EAP. In this workshop Olwyn Alexander and Sue Argent show how EAP is different from ELT by comparing how the two approaches would deal with the same topic using different texts and tasks, thus contrasting the ways in which the two approaches specify needs, formulate aims and judge the effectiveness of a lesson.
