The Center for Global Geography Education (CGGE) is a set of online modules exploring geographic issues, which allow collaborative analysis and discussion between international teams of undergraduates. Using data from trials held in 10 countries, the modules' effectiveness in improving student understanding of geographic concepts and appreciation for cross-cultural perspectives on the issues were evaluated. Analysis of qualitative and quantitative data revealed that CGGE achieved its aims of enhancing geographic knowledge and skills. The modules and their international collaboration design inspired high interest among students and professors. Specific revisions to their content are identified in order to foster deeper exchanges of international perspectives among university students. (Contains 4 figures, 4 tables, and 3 notes.)
