It starts with discussing some basic and preliminary principles of materials design followed by scrutinizing critical issues in materials development in an objective and systematic way. This ranges from considering learners’ needs, adopting, adapting, selection, and gradation of materials to the specific focus of the book on developing various types of materials for the four language skills, pronunciation, ESP vocabulary, and computer assisted language learning materials. Authenticity of materials to be designed and the inclusion of affective factors to develop motivating materials to engage language learners, in addition to features of materials design at a universal level are other areas to read about. This book finally tries to open new horizons and possible futuristic approaches to improve today’s ELT materials.
