Educational technology is becoming more pervasive in Indonesian vocational higher institutions, yet there is limited research available about Indonesian teachers' perceptions of this innovation. This paper sets out to contribute to this gap in the research literature and reports on a study that investigated the factors which supported and constrained the use of educational technology at an Indonesian polytechnic. Data were gathered from 10 teachers working full-time at the polytechnic using semi-structured interviews and were analysed using thematic analysis strategy. The findings confirm previous research in Western countries which suggest that factors including teachers' beliefs and attitudes, organizational culture and external influences can have a significant influence on the integration of educational technology to support learning and teaching. The study also identified that factors such as skills, workload, strategic planning, ownership, resources, professional development and leadership require attention as they can have a negative influence on successful integration.
