Int'l Ed is a cover term for all sorts:
-the int'l studies schools assocation (issa) out of Denver U is about the geopolitical rather than the interpersonal details of language/culture
-others interchange 'global studies' with int'l ed to mean One System, One Standard (homogenization)
-MIIIE (Midwest Institute for Int'l Intercultural Educ, www.miiie.org) features travel opportunities, exchanges, thematic workshops for its 100 community college member.
-k12 classrooms tend to accept "countries, capitals, holidays and flags" as int'l education
As an anthropologist with a desire to popularize the perspective and apply to daily life situations, my view of int'l education is something practical: experiencing the feeling of being outside vs inside one's culture, finding ways to communicate when words are limited (non-native speakers to native speakers), know a few basic facts about translation (limitations) and the connections of language to culture and interpersonal relations. Also some facts from archeology and from physical anthro should be widely know among all school children (not to mention their parents and their teachers).
So my approach is infusion (adding some insights, examples or comparative content to the existing lesson plans during the school year --- for all subjects, including art, math, sport, music)
