Blended learning, a teaching method that has been around for quite some time globally, has become an essential requirement in Vietnam since the outbreak of the COVID-19 pandemic. However, organizing and implementing blended learning face numerous challenges. To gain a more comprehensive understanding of the current situation and recommend policies for developing blended learning in higher education, we surveyed 1138 students from three different universities and colleges in Ho Chi Minh City. Compared with qualitative research results from practical experience, the analysis of survey data reveals that students highly appreciate the advantages and benefits of blended learning in the current digital transformation context. However, several challenges also emerge: Direct interaction between instructors and students has decreased, which impacts the quality of learning experiences; students' skills in selecting learning activities and self-managing their studies need improvement; there is a lack of effective and safe quality management systems for teaching; insufficient synchronized equipment and devices hinder effective online learning; some students feel pressured by academic requirements, but lack proper supervision, affecting their motivation and study habits. The choice of blended learning processes varies significantly based on the field of study and the conditions of each institution. We recommend a comprehensive government strategy for blended learning to address these challenges. This strategy should focus on motivating and training students, providing social information technology infrastructure, and developing digital content within educational institutions. These macro-level policies are crucial for advancing blended learning in Vietnamese higher education.
