This thesis aims to learn about opportunities for and challenges to the development of multilingual literacies in three forms of education in Sweden and Australia that teach or draw on immigrant languages. In Sweden mother tongue instruction and multilingual study guidance are in focus and in Australia, a community language school.

Taking an ecological approach to the research sites, the thesis investigates how language ideologies, organization of the form of education and language practices impact on the development of multilingual literacies. A range of linguistic ethnographic data including 75 lesson observations, 48 interviews, field notes and photographs has been analyzed against the theoretical backdrop of the continua of biliteracy (Hornberger, 1989; Hornberger & Skilton-Sylvester, 2000), heteroglossia (Bakhtin, 1981) and emerging theories of translanguaging (García & Li, 2014) to investigate the questions. The thesis ties together the results of four interlocking case studies investigating the above-mentioned forms of education.
