UNITEC’s short history in the field of online learning provides a story of changing attitudes and usage at three levels organisational, tutorial and student. From the first course designed for flexible delivery in 1994, UNITEC has progressed through three distinct phases of course development. As of the middle of 2001, UNITEC has over 300 courses that are completely online, or have some element of online delivery or support for students, ranging across all five academic faculties. To support this rapid increase in the use of the medium, a number of organisational changes have been made, along with a programme of professional development and tutor and student support. This paper looks briefly at the process of growth, and the changing nature of ongoing tutor development. There have been significant changes in the way tutors use the course delivery interface and the professional development programme has tended towards more active support of the issues of teaching and learning. We report on some of the lessons learned, the difficulties that have arisen, and look at some of the challenges for the future.
