This paper examines the dominant knowledge construction in Canadian public schools. Using the grounded theory approach, thirty-six Chinese Canadian youths and young adults were interviewed in Alberta. Drawing on critical, anticolonial and Bourdieusian perspectives, I argue that some teachers' racialised habitus and biased knowledge constructions devalued the indigenous knowledges that immigrant youth bring to the classroom. Moreover, they reproduced anti-immigrant discourses and reinforced racial hierarchies in Canadian society. As a consequence, they negatively affect the identity construction of immigrant descendants and undermine their attempts to negotiate a sense of belonging in Canada. I argue that decolonising dominant knowledge constructions requires challenging teachers' racialised habitus in teaching and their interactions with immigrant students.
