This thesis explores being a White, Western, native English-speaking teacher in encounter with students perceived as different. Conducted as an interview and observation study in three international schools in Vietnam, it focuses specifically on the constructions of difference in representations of teacher and student, Westerner and Asian, and Self and Other in teachers' discourse. Plugging in to the works of Gilles Deleuze, Gilles Deleuze and Felix Guattari, Michel Foucault, Jacques Derrida, and Homi K. Bhabha among others, it argues that the position of the teacher is ultimately paradoxical and paranoid, constituted by the desire for an Other who both desires the teacher and concomitantly expresses the constant threat of the erasure of the teacher through the very act of being taught.Inspired by the deconstructive critique of enlightenment humanism, the thesis also explores the problem of how to think and write about subjects who are not given as such. That is, rather than autonomous, integral, agentic individuals, teachers and students are represented as heterogeneous elements entangled in an assemblage of forces and intensities in which the individual cannot be reliably individuated, interviewed, observed, and subsequently analysed, interpreted, and discussed.Thus the thesis is an attempt to think and write within the flow of forces and intensities that comprise the assemblage, and of which the researcher and thesis are also a part, resulting in a text which may strain at the limits of recognisability as thesis per the conventional expectations of humanist qualitative inquiry.Consequently the thesis also represents an experiment in and with writing, an exploration of the limits of what is possible within the constraints of the thesis text, and an attempt to do something other than the methodical application of the conventional. As such it is only ever a partial representation of the real, or rather an experiment in contact with the real. An attempt to write when writing is thinking and thinking is the creation of something that may not have previously existed.
