This chapter is divided into two sections. The first focuses on the research methodology employed in this project. This section clearly outlines the reasons for the methodology undertaken, how the schools were chosen, and how students were selected to take part in the study. It looks at the different worldviews (Guba & Lincoln, 2005) available and justifies the approach adopted in this study. The second section looks more closely at the way students’ personal identities develop. As noted by Best (2011), the study of youth identity is carried out over several disciplines. These include cultural studies, anthropology, psychology, sociology, education, English and history. A number of key longitudinal studies have been undertaken in the last ten years relating to identity and belonging. These show how personal identity formation takes place in adolescents and how the various disciplines help to conceptually frame the notion of global identity. Both sections combine to show the key methodological and developmental understandings underpinning this unique study.
