When an exchange teacher instructs her students in her native language, she provides invaluable instruction into correct accent, idiomatic expressions and regional dialects. In the course of discussing foreign expressions, social speech and mannerisms, and history, the teacher also gives important insight into the shape and values of her culture. Her explanations of cultural references also reveal to her students the history, work philosophy, religions, everyday life and traditions of her country or region.
The technical and professional expertise of a foreign teacher can provide a valuable perspective on working interculturally and insight into the international marketplace. The relative geographic isolation of the United States, Australia and Canada, for example, compared to countries on other continents, leaves a student who has not traveled widely less knowledgable as to how people from other cultures think and work. An international perspective on a particular industry or area of study can be vital for preparing students to work within a global market.
Students also benefit from the new and positive educational practices of an exchange teacher. As the exchange teacher mixes with staff at his host school or college, each shares information on programs and teaching skills at their respective schools. The Fulbright teacher exchange, for instance, aims to create ongoing relationships between schools. The international learning and relationships that can result provide students with a broader view of their subject area while giving it an international context.
As an ambassador for her country, a foreign exchange teacher's own comments, views and opinions, in addition to any technical or other academic knowledge that she contributes, will afford students an invaluable look into another country and worldview. In the case of an American teacher working abroad, the generally negative view that many young people in foreign cultures have toward Americans can be countered by the presence of a well-read, intelligent, polite American who represents her country in a positive way.
