This study aims to assess the current status of digital technology-based teaching and learning at Doan Thi Diem Primary School in Hanoi using a mixed-methods approach, combining a survey of 45 school administrators and teachers with in-depth interviews with 10 participants. The study focuses on four aspects: (1) determining teaching and learning objectives; (2) developing lesson plans; (3) implementing lesson plans; and (4) assessment and evaluation. The findings show that the school has achieved positive results in generating lesson ideas, designing presentation-based lessons, digitizing certain grading processes, and organizing engaging warm-up activities. However, several limitations remain, including inadequate and non-integrated classroom infrastructure and equipment, fragmented management data systems, and teachers’ limited advanced digital technology application skills. The findings provide empirical evidence on digital technology-based teaching and learning in a private primary school and suggest directions for improving the effectiveness of digital transformation in primary education.
