Published in 1978, this is a concise and practical guide to the use of linguistic theory and analytical techniques in English language teaching at secondary and tertiary levels of education. Much has been written in this area in the past, but previous emphasis has most often been theoretical. This book is concerned with the realities of teaching, and each technique recommended is explained by reference to actual examples of students’ writing and speech. The underlying theory is discussed only when this serves to clarify practice. John Keen demonstrates how students’ existing grasp of the uses and processes of English can provide a reliable base from which to develop their language skills in a meaningful and effective way. His own experience has convinced him that the sympathetic use of linguistic insights can help in teaching the conventions of spelling and grammar, developing students’ sensitivity to meaning in language and enabling them to use language resourcefully in a variety of contexts – including writing coherently and at length on particular topics. The Bullock Report recommended that language study should be part of every teacher’s training. This book indicates some directions that such a language study might take.
