The COVID-19 pandemic has caused universities to switch from traditional to online teaching and learning methods. As a result, social media has gradually become prominent as a teaching and learning resource in universities. Vietnamese universities and institutes recognize the potential of social media as a powerful tool for promotion and teaching. This study examines the positive impact of social media use on (a) enhancing teaching and learning in universities, (b) motivating and supporting students, and (c) developing community connections and assesses limitations of social networks in student learning within the university context. A qualitative approach with explicitly utilizing in-depth interviews was employed to collect data from ten lecturers and 19 students of all faculties of Van Hien University.
