This qualitative study investigates the strategies employed by Vietnamese tertiary-level English as a Foreign Language (EFL) teachers to promote learner autonomy (LA) and enhance cultural awareness. This research provides a deeper understanding of EFL teaching practices in this setting, conducted in the context of Vietnam’s evolving educational landscape, where English proficiency and cultural competence are increasingly prioritized. The study utilized semi-structured interviews with nine EFL teachers from two different Vietnamese tertiary institutions, representing various career stages: novice, mid-career, and near-end career. Thematic analysis was employed to analyze the data, revealing a range of strategies encompassing collaborative learning, technology integration, personalized feedback, real-life scenarios and role-play, reflective learning practices, local culture incorporation, contextualized language instruction, critical thinking, and cultural analysis, student-centered environments, interdisciplinary approaches, language skills for intercultural communication, and authentic material use. Findings highlight the multifaceted nature of language teaching, emphasizing not just linguistic competence but also cultural understanding and LA. These strategies are crucial in a globalized world where intercultural communication is a key skill. The study suggests the need for continuous professional development and policy support for diverse and holistic teaching practices. It offers practical insights for EFL educators, particularly in similar socio-cultural contexts, on integrating various strategies to enhance language skills and cultural awareness.
