This series of 16 books for adults covers the four skill areas of listening, speaking, reading and writing at four levels, elementary, intermediate, upper-intermediate and advanced. The series maintains the traditional division of language use into the four skills, but they are never treated in isolation. In each book, the skill being dealt with serves as the focus of attention and is always interwoven with, and supported by, other skills. The materials are intended to be creative, presenting the students with motivating material; fluency-focused, bringing in accuracy work only in so far as it is necessary to the completion of an activity; task-based and focused on problem-solving, motivating students to use language in an active and practical way, as well as relating the tasks to the students' own experiences. "Oxford Supplementary Skills" can be used as a supplement to a core course book for extra practice and also as modular course material, offering the teacher scope for flexibility. Each book contains, where appropriate, teacher's notes, a key and the text of the recordings. All the "Listening" and some of the "Speaking" books have accompanying cassettes. - from Amzon
