WebEnglish.se added a link to The Peace Corps’ free publication called Cross-Cultural Workbook. The author has used selected parts of the 266-page pdf-book in her teaching and recommends the material to be used to learn about the concept of culture. It suits well together with the studies of English Speaking Countries or as a separate theme. Understanding the concept of culture is an essential part of internationalisation, which is one of the four perspectives that the Swedish curriculum, Lgr11, stipulates to be permeated in all teaching “It is important to have an international perspective, to be able to understand one’s own reality in a global context and to create international solidarity, as well as prepare for a society with close contacts across cultural and national borders. Having an international perspective also involves developing an understanding of cultural diversity within the country.” (Lgr11, p. 12)
The Peace Corps have also published a Classroom Guide to go with the Workbook.
