The acquisition of a living Second Foreign Language (German, Spanish, French, Russian, etc.) gains more weight in the near future for Taiwanese Junior and Senior High School students. Nevertheless, the methodology of teaching a second foreign language differs significantly from the acquisition of English as the first second language.(This approach ist called: Foreign Language Teaching after English as a First Foreign Language) Three major reasons do underline this statement: Before learning a second foreign language all students have to learn English. Consequently, teachers of any other European language are confronted not only with linguistic interference of Chinese but also – and mainly - of English. The teacher is also confronted with already fossilized habits of foreign language learning. Furthermore, the time given to learn a second foreign language is limited. Those reasons leads to the conclusion, that teaching (and learning) of a second foreign language differs from teaching English as the major first foreign language esp. in Taiwan and in order to keep up with the need of further foreign language acquisition this course is offered.
