In this paper, I describe a methodology that I employed, and resultant methods that I designed, to facilitate a Critical Discourse Analysis exploring perspectives on Western modern science as a school subject discipline in a given Caribbean context. Using specific themes from post-colonial theory, I sought to engage with some of the viewpoints presented by key stakeholders in secondary science education in the research setting. This paper reports on the methodological framework for the research study, illustrating some of the philosophical challenges encountered during the development of the research methods. Specifically, I discuss the tensions associated with the pursuit of researcher legitimacy, the use of 'scientific' methods of inquiry in a work that seeks to be decolonizing, and the challenge of stimulating conversation about a topic for which participants might not possess readily formulated opinions. My response to these challenges resulted in methods that utilized a unique adaptation of Stephenson's Q methodology. Although these tensions are far from being fully resolved, the approach outlined helps contribute to our understanding of the complexities of negotiation that can occur when conducting research of this nature.
