The authors describe teacher professional identity as lived experience in the context of educational change. Adopting activity theory and its genesis in cultural historical theory (Stetsenko & Arievitch, 2004) as a framework, the article discusses the way teachers see themselves as professionals and how they compose their identities in schools, the educational space, which is their workplace. Activity theory is utilised as the broad theoretical lens and the design type and methodology are discussed accordingly. The school and the classroom are activity systems (Engeström, 1991), and social and semiotic ecosystems (Lemke, 1995). It is therefore in the tensions within the activity system that we capture and represent a constructed teacher conversation, composed of the voices of three social actors on an imaginary social stage, which is the empirical text of the article. Main findings speak to multiple roles, struggling voice and forging professional identity in the changing educational landscape.This article attends to teacher identity as lived experience in the context of educational change. In a young democracy such as South Africa, teachers play a critical role in educating the youth and advancing the social collective good. We argue that, in a society where the social capital divide is increasing, teachers are one of the last hopes for the young from especially rural and poor township communities. Adopting activity theory and its genesis in cultural historical theory (Stetsenko & Arievitch, 2004) as a framework, the article discusses the way teachers see themselves as professionals and how they compose their identities in schools, the educational space, their workplace. This workplace is neither fixed nor static, but a site for intersecting networks of relations, technology (tools) and practice which extend in complex interrelations beyond what is seen as the institution (McGregor, 2003). All of these aspects are enlarged in a society in transition where there are numerous structural and semiotic changes.
