Interchange is a three-level course for learners of English as a foreign language. Written in American English, Interchange reflects the fact that English is a language of international communication. The multi-skills syllabus on which the course is based integrates structural, functional, lexical, phonological, situational and thematic syllabuses, while the methodology emphasises a communicative approach, focusing on both accuracy and fluency. Interchange is attractively designed to appeal to adult and young adult learners who want a course that provides them with extensive opportunities to express their own ideas and opinions, while developing the skills they need to communicate effectively in English.Key Features of the Course are: Snapshots' contain interesting real-world information to stimulate thought and discussion related to the themes of the units; Conversations present structures and functions in a situational context and serve as language models for speaking tasks; Word Power' exercises present and practice key language used in each unit; Pair work, group work, and role-play activities provide freer and more personalised practice of the language; All four skills are developed through discrete exercises and within integrated activities; Special tasks called Interchange activities' provide a communicative extension to each unit, allowing learners to use the language they have acquired in creative ways; Review units after every three units review and recycle material; Tests accompanying the review units are in the teacher's book and are photocopiable; Interchange was field-tested widely in many countries before publication Level 1 takes learners from false-beginner to low-intermediate level, presenting and practising basic language items with opportunities for personalisation right from the start.
