ABSTRACT Addressing the issue of colonial humanism ideologies plaguing undergraduate thesis work of English pre-service teachers in the Indonesian context and perpetuating the dichotomy of teacher and researcher identities, this study explored two pre-service teachers’ entanglements in their day-to-day praxes of undergraduate thesis work as a site of identity construction by framing it in the lens of postcolonial, posthuman and transnational Cultural-Historical Activity Theory. Orienting toward movement of actions and praxes, they actively participated in entanglements of identity construction by making visible layers of contradictions and continuously maneuvering the contradictions to achieve meaningful outcomes in each praxis. The contradictions at the micro level further revealed contradictions at the meso level of actions and the macro level of networked activity systems at the institutional level, indicating the pivotal role of understanding their micro level of praxes to unveil issues hindering undergraduate thesis to serve as a democratic space to generate meaningful knowledge.
