This paper describes findings from a 2002-03 research project which sought to establish what the barriers were to the adoption or extended use of the centrally supported online learning management and content creation system by academic staff at the University of Adelaide. The research was conducted using semi-structured interviews and a survey administered to all teaching staff at the University. The survey canvassed respondents' use of and the value they placed on web supported teaching (particularly the centrally supported learning management system MyUni) and barriers to its adoption and further use. Respondents reported a higher valuing of and future intention to use than their current use of the Internet to support teaching. Factors that constrained their adoption or expanded use of web supported teaching included time and workload pressures, concerns about knowledge and skills, conceptions of teaching and the value of web supported learning for improving student outcomes, and the perceived stability and integration of the University infrastructure and learning management system. Respondents' views of priorities in addressing these concerns related to improved support from the University for web supported teaching, including staff development and training, IT and administrative support, and management support. This paper discusses some staff development implications of the findings. (Contains 7 tables.)
