It is on the spotlight currently in education regarding how to nurture global competence in K-12. The study proposes the learning genre of global networked collaborative project-based learning for meeting the goal. The genre places students in a virtual learning environment with a global context and encourage them to deal with sustainable development goals, which was initiated by United Nations in 2015, in a joint effort collaboratively. The goal of the study is to verify by incorporating empirical methodologies whether the genre could foster global competence or not? First, four designated project-based learning courses were designed and implemented on a renown international collaborative learning platform. International participants then were recruited in an open manner and took part in the learning tasks of the courses online for 10 weeks in a team-based format. For assessing the performance in global competence, a rubric was developed and administered in pretest and posttest fashion, which were responded by teachers of the participating teams for all team members individually before and after the courses respectively. The criteria of the rubric are composed of four pillars, which are Investigate the World, Recognize Perspectives, Communicate Ideas, and Take Action. Results of the data analysis reveal that the proposed learning genre raises global competence significantly.
