Every language teacher is automatically a teacher of culture. The language teacher is an instructor of culture in the same way that an instructor of history or anthropology teaches those disciplines. To prepare for teaching the culture, the training of language teachers should include pre-service and in-service activities and materials specifically related to the culture, in addition to the learning of the language itself. Cross-cultural training for language teachers might also be helpful. The inclusion of such activities and materials suggests that the current four-year teacher training program will require some adjustment in both time and required content to provide the necessary background. These changes also suggest the need for closer cooperation between teacher trainers and those in other disciplines. One major question about the "how" of instruction concerns the extent of the use of the mother tongue. In general, one could apply the principle that the more knowledge of the target language the students have, the more they can benefit from instruction in the language. As far as the "when" of teaching culture is concerned, teachers should be aware that they are teaching culture at all stages. (SW)
