Several higher education institutions in Vietnam are gradually adopting this approach in recent years, although SL has been widely applied in the Western education system since the 1990s. By doing a narrative literature review, this paper aims to clarify the benefits and challenges of embedding SL in training social science subjects in high education, especially regarding mechanisms to promote participation among relevant stakeholders, including lecturers, communities and students. Through the analysis, the benefits of SL are well-equipping students with the basic knowledge of the subjects, methodology and commitment to civic responsibility. Service-Learning allows educational institutions and lecturers to enhance efficacy, effectiveness and performing social responsibility. Community members directly benefit from SL projects. Some challenges in applying SL include the need for clarity in distinguishing between volunteer work, internships and SL, resulting in the inaccurate assessment of the roles and the concerns of different stakeholders in SL. Regarding participation, there are two main challenges. The first challenge concerns organising work and effective communication between the community, universities and students. The second is about stakeholder engagement and their actual performance in SL cooperation. This paper proposes setting up an SL department as a facilitator for supporting lecturers, connecting relevant departments in the University and connecting the University with the community.</em></p> 2023-08-03T00:00:00+07:00 Copyright (c) 2023 Van Hien University Journal of Science https://js.vhu.edu.vn/index.php/vhujs/article/view/734 A systematic review on flipped classrooms in English language teaching in Vietnam 2023-08-18T20:07:30+07:00 Nguyen Thi Mo mont@vhu.edu.vn <p><em>The purpose of this research is to provide a systematic review on the flipped classroom (FL) approach in English language teaching (ELT) in Vietnam in terms of the trends and the key results, based on 12 published articles. A content analysis method was employed to analyze the collected papers. The findings indicated that the implementation of flipped learning appeared to gradually increase in Vietnam since 2017 and remain its prosperity in the higher education context. Also, the results revealed that a variety of research methods were used in selected articles; however, the most common one was the mixed method. Moreover, grammar and speaking skills were the two basic language skills being commonly studied. Additionally, the flipped learning was shown to not only produce an improvement on learners’ achievement but also positively affect their perspectives toward its application.
