This paper presents an analysis of my experiences with a teaching activity that engages students in publishing in Wikipedia on issues relating to globalization. It begins with a short overview of some of the current debates revolving around teaching globalization, which lay ground for the assignment. I discuss how this teaching tool fits with a number of dimensions related to teaching globalization, particularly with an international service learning approach. Finally, I present assessment data from a series of surveys I conducted from 2008 to 2016 on the effectiveness of the assignment.
