This guidebook brings into sharp focus some effective techniques for teaching vocabulary, grammar, reading, writing, listening, speaking, and language learning strategies at primary, secondary, and collegiate levels. Some effective guidelines have also been provided for Online Teaching. Importantly, the mechanisms underlying the implementation of CTBL, Dr Hosseini¿s instructional innovation, as well as presentations and classroom techniques in classes where this approach may be applied have been illustrated. Dr Hosseini¿s sample lesson plans and CV have also found a place in this book. This must-read guidebook will be of immense help to whoever wants to teach language. It is helpful particularly to ELT students, language teachers at all levels, and in-service programmes for instructors / T.T.C. crash courses.
