Since the late 1980s and early 1990s, Comparative and International Education (CIE) has almost disappeared from the curricula of teacher education colleges in Ireland, the United Kingdom and the United States. Yet, CIE is experiencing a revival at postgraduate level. This article will explore the reasons for this dichotomy and the decline of CIE in initial teacher education. It will use findings from a research study in an Irish teacher education college to inform this exploration. The author initiated, developed, and offered a CIE course to final year BEd (n = 24) students in 2003 and again in 2005. This article will use data gathered during the latter course to explore CIE for undergraduate trainee teachers, considering students' motivation for choosing to study CIE, their perceptions of CIE, and their beliefs about how it may enhance their professional practice in classrooms. It will explore, in particular, a significant finding that emerged from the study--the potential of CIE in developing student teachers' capacities to teach in multicultural classrooms.
