There is a growing interest in the monitoring and evaluation of Education for Sustainable Development and Global Citizenship (ESD/GC). This chapter offers a methodological reflection on researching what is valuable in global learning approaches to Science, Technology, Engineering and Mathematics (STEM) school-based practice. The authors offer a methodological reflection and learning from the Make the Link project that involved non-state educators and teachers working together to incorporate development education and global learning in STEM curricula.
