As part of a course on Intercultural Awareness that I took at Norwich University in Summer 2011 we produced some materials. I believe the first Power Point was provided by Silivia's team and the second by the Facilitator, Uwe Pol.
This link HERE contains two Power Points to help students understand how road and street signs are permeated with the politeness notes that characterizes British people
As an example of the content of the slide show, students will learn what this booth is for. If you want to know, download the second PowerPoint and find it out.
