Achieving higher levels of proficiency in a foreign language depends on more than an extensive knowledge of grammar and vocabulary. Evidence is mounting that true proficiency depends on cultural awareness about how and when language is used. This suggests that teachers in foreign language classrooms must incorporate explicit cultural lessons into their teaching plans. Yet, there remains a stubborn resistance to doing so. This paper outlines the main reasons in teaching culture and how cultural instruction and awareness lead to increased intercultural communicative competence (ICC). It addresses teachers' concerns about teaching culture and outlines their roles. The paper provides a strategy for designing successful activities that will build intercultural communicative competence and critical thinking skills.
