This book examines the relationship between learner motivation and cultural contents for the teaching of English as a Foreign Language. It takes Chile as an example of the «Expanding Circle of English», where the 21st century has brought new challenges to English teaching. After providing background information on the presence of English in Latin America and Chile, this qualitative study includes the analysis of curricular frameworks, textbooks and teacher interviews. Conclusions propose an explicit, yet critical inclusion of both motivational strategies and cultural themes into educational and curricular policies, learning materials, and teacher training.
