This UNESCO source book concerns the development of the teaching of English as the language of instruction in English-speaking Africa with particular attention to the problems of the secondary school course. It is intended primarily for African educators in senior positions who have not had a chance to receive formal training in teaching English as a second language. The various chapters concern issues which are vital to an English-as-a-second-language course at the secondary level: aims and attitudes, vocabulary selection and the grading of teaching materials, reading, writing, study skills, grammar, speech, drama, and poetry. The author stresses the importance of a solid foundation in the first year of a student's English study. The final chapter offers suggestions for preparing students for the School Certificate test when they have not had an adequate introduction to English. Appendixes concern audiovisual aids, English language testing, and recommended reading. (VM)
