Although technology has been seamlessly integrated into classroom teaching, there is room for improvement in the way professional development is implemented. The aim of this study was to explore the experiences of Thai teachers of English as a Foreign Language (EFL) in implementing digital literacy training. Focusing on technologically illiterate teachers (and particularly older ones), the study aimed to investigate the production of online videos by these teachers to be used in their classrooms. The study was conducted in Trang, Thailand, and involved 36 Thai EFL teachers who underwent a one-month training programme in 2020. Data was collected through a questionnaire, observation, and interviews. The results showed that the participants required additional training time, and faced challenges such as teaching style, computer specifications, and Internet accessibility. Despite these challenges, the teachers reported a positive perceptions of teaching English with technology, and found it was easier than they had anticipated. These findings have pedagogical implications for future implementations of digital literacy training for somewhat technologically illiterate language teachers.
