Abstract: The chapter is a critical appraisal of bilingual education policy scholarship and practice against a backdrop of contestations that characterize determination and
execution of bilingual education goals and the spread of the idea of linguistic
human rights in education – and discourses attendant and consequent to these
processes. A dominant and recurrent motif in bilingual education policy discourses
is the assumed analogous relationship between language and the
nation-state and the sometimes integrative, sometimes disruptive role of education
in this relationship. Resultant bilingual education types have, in practice,
manifested themselves in a range of programs. Invariably, these programs fall
within a dyad of language policy orientations, these being promotion/tolerance
and repressive/restrictive. These orientations influence types of educational programs
and their outcomes. Nowhere are these dynamics more pronounced than in
postcolonial contexts – which, from the critical perspective adopted in the
chapter, include, apart from the “usual” contexts in the global south, western
democracies with a colonial past. In these contexts, presumed “mother tongue,”
local language, or minority language becomes both important and problematic in
the conceptualization and implementation of bilingual education policies. In other
instances, even when language-in-education policies are allegedly intended to
increase opportunities for educational access and equity, in practice, they (re)
produce, perpetuate, and entrench unintended outcomes largely inimical to the
progressive goals of bilingual education policies. However, when effectively
implemented, bilingual education policies remain potent tools for social, political,
and economic inclusion of marginalized groups in postcolonial contexts,
irrespective of whether these are in the global north or global south.
