Finally, what can we say about Emma's communicative needs? Emma would probably not need to use formal speech very often in her day to day work, but her ability to interact socially using appropriate language with a range of people of different ages will be fundamental to her success as a hairdresser. She would need to express interest in her customers' lives, to speak with her employer and her work mates as well as with other professionals in the hairdressing industry.
When James graduates as an engineer, for example, he would need to communicate with his employers, perhaps an engineering firm, with their clients (builders, project managers, government departments, local councils). In these situations, his ability to express his ideas would be fundamental to his winning project tenders.
James' communicative environment will require very different language skills from those of Emma. He would need to learn the language of his field of study, eg, engineering. He will also need to learn a range of general academic terms or language for learning. James would also need to contribute to discussions and to give formal presentations. Like Emma, he too would need to communicate with a range of people, but the sort of communication expected of him would be very different from that expected of Emma. James would have to talk to lecturers, tutors, library staff (usually about his subject area), and other general administrative staff (usually about his enrolment, prerequisites, electives etc). Communicative competence for James would also be fundamental to his success as an engineer. He would need to negotiate with clients and to gain their confidence and custom through the expression of his ideas.
