This study seeks to conduct a multi-layered examination of language ideologies in English-medium instruction (EMI) education anchored in policy documents and relevant stakeholders’ discourse in Vietnam. Research data were based on national and institutional policies and interviews with ten university administrators, 15 content lecturers, and five focus groups of six students. The findings indicate that EMI is ideologically embraced as producing different forms of capital, including linguistic, cultural, economic, and social capital, all of which have enormous potential for the cause of national socio-economic development, internationalization of higher education, and individual future employability. However, the study demonstrates that the way EMI is celebrated and glorified as access to supreme quality education unexpectedly gives it symbolic power and undoubtedly downgrades the mother tongue as a medium of instruction. The study is concluded with implications and recommendations for further research on language ideologies in EMI education.

越南英语教学的意识形态

本研究旨在对以越南政策文件和相关利益相关者的话语为基础的英语教学（EMI）教育中的语言意识形态进行多层次的研究。研究数据基于国家和机构政策以及对 10 名大学管理人员、15 名内容讲师和 5 个由 6 名学生组成的焦点小组的采访。研究结果表明，EMI在意识形态上被认为可以产生不同形式的资本，包括语言资本、文化资本、经济资本和社会资本，所有这些资本对于国家社会经济发展事业、高等教育国际化和个人未来都具有巨大潜力。就业能力。然而，研究表明，EMI 被庆祝和美化为获得最高质量教育的方式意外地赋予了它象征性的力量，毫无疑问降低了母语作为教学媒介的地位。本研究的结论对 EMI 教育中语言意识形态的进一步研究提出了启示和建议。
