Tóm tắt

In higher education, integrating sustainability-related issues into teaching has attracted growing attention as a meaningful way to develop students’ academic communication and critical thinking. This study investigates the impact of sustainability-themed English for Specific Purposes (ESP) instruction on the debate competence of B2-level students at Hanoi University. The study employed a classroom action research design with a mixed-methods approach. Data were collected through pre-, mid-, and postcourse debate assessments, a post-course questionnaire, and open-ended student reflections. Quantitative data were analyzed using descriptive statistics and paired-samples t-tests, while qualitative data were examined through thematic analysis. The results show significant improvement in students’ debate competence, particularly in fluency, coherence, argument development, and use of evidence. Students also reported higher levels of participation and greater confidence in expressing ideas in academic discussions. The findings suggest that integrating sustainability themes into ESP instruction can support the development of students’ language proficiency, critical thinking, and social awareness, and offer practical implications for incorporating sustainability-related topics into language teaching in higher education.
