Eighteen VET practitioners considered to be at the leading edge of online education in technical and further education in South Australia were interviewed to determine the extent of their knowledge about and experiences of online learning and teaching. Data were gathered through a survey, structured interviews, online research events, and two face-to-face workshops. Responses indicated that, despite a VET policy environment keen to accelerate the take-up of online learning, online teaching and learning remains a very new area of human endeavor and a new area for VET policy and practice. The practitioners were actively involved in constructing knowledge about online learning. However, they were not yet systematically or consciously reflecting on the inferences to be drawn from their individual and collective experiences. Although the practitioners were excited and challenged by their online activities, they were also frustrated and pressured by lack of time, infrastructure, and resources. The practitioners' four main sources of professional learning about online teaching and learning were as follows: learning by doing; learning through work colleagues and teamwork; learning through communities of practice; and learning through formal off-the-job professional development. Organizational culture, policies, and structures played a big role in the VET practitioners' adoption and implementation of online VET. (MN)
