Owing to the impacts brought by globalization, global education training the students to become global citizens that adapt to the future and promoting a fair and everlasting world. Global education is the common goal among different subjects, but geography is beneficial to the realization of global education because it contains a characteristic of a global view. Moreover, the 2009 curriculum outline of senior high school for geography also indicates “Students should show their concerns toward global issues actively” as the ultimate goal. However, the geographic teaching in senior high schools in Taiwan has long laid emphasis on cognition. It’s more difficult to sharpen learners’ acquisition of global vision only by means of lecturing. To fortify the teaching goal of teaching geography in global education, this study consults the experience of Online Center for Global Geography Education (CGGE) in America, and develops a global education teaching model for geography teaching in senior schools. To create the learning situation of global conflict and cooperation, we chose the Taiwan and Mainland China trade issue, similar language culture, depend but compete mutually, after referring the internet cooperative learning experiments. In response to the purpose of global education, the teaching model applied cross-strait Internet cooperative learning and issue-based strategies to lead students to investigate and discuss the world through the perspective of geography and to facilitate students’ ability in cooperation, critical thinking, respecting multicultural and facing confrontation. XOOPS offers a free learning platform. The research adopts quasi-experimental design worked out by two ordinary high schools in Mainland China and Taiwan, including 102 students. Through the analysis of course quality discussion and the attitude inventory, students really improve their academic performances in global education. 67% of the learners agree that the course is worth popularizing to other schools and implementing. However, due to the differences of the Internet learning environment for senior high school students between both sides of Taiwan Strait, applying curriculums with “open” learning devices in teaching is recommended.
