The global increase of the incorporation of Global Citizenship Education (GCE) related contents in education systems in recent decades has generated a vast body of scholarship, both empirical and theoretical. An explanation for the rise in GCE internationally is often described as a response to economic, social and political changes that have made countries more interconnected through enhanced international mobility and financial interdependency. Globalization is claimed to lead to more diverse societies that require engagement with broader, more inclusive conceptions of citizenship, thus leading to the need of incorporation GCE into national curricula to various extents. As scholarship in this field had developed accordingly, there is a need for a systematic analysis of the topics and sub-fields that emerged and examined within this broad concept.
We performed a systematic review of research dealing with Global Citizenship Education (GCE) between 2006-2017 using Natural Language Processing (NLP) followed by network analysis to record and interpret the development of this field of research and highlight the trajectories of the current academic scholarship within teachers’ education. The analysis showed how studies surrounding GCE being discussed in the scholarship, forming intricate, and encompassing distinct areas such as education for sustainable development and critical thinking. We also highlight some notable omissions in the contemporary research, topics that appear to be under-represented in the research on GCE. Considering the rising interest in GCE, understanding the current research landscape could be useful for policy-makers, educators and scholars who seek to build upon the existing body of knowledge and develop it in new directions.
