In this regard, it starts with analysing students? needs in terms of the English language knowledge and skills they need in order to function effectively through the English medium of instruction. Then, it analyses the one year English course materials to consider the extent to which they address the academic preparation of students on the course. Furthermore, it investigates students? and teachers? perceptions about the helpfulness of the course. it finally proposes an adjustment of the course towards English for Academic Purposes. This book is mainly useful for both English and content subjects teachers and learners in contexts where English as a foreign language is used as the language of instruction.
