There is currently strong recognition within the field of intercultural language teaching of the need for language learners to develop the ability to actively interpret and critically reflect on cultural meanings and representations from a variety of perspectives. This article argues that cultural representations contained in language textbooks, though often problematic, can be used as a useful resource for helping learners develop their capacities for interpretation and critical reflection. The paper draws on data collected in an English language classroom in Japan to highlight some of the ways that language learners construct critical accounts of cultural content in a language textbook, highlighting not only the content of their accounts but also the discursive strategies they use to construct them. It therefore illustrates the potential for working with imperfect materials to develop intercultural competencies.
