Four models of online teaching are currently being used within the Faculty of Informatics and Communications at Central Queensland University in Australia. The naive model, which is the most widely used, may be characterized as "putting lecture notes on the World Wide Web" with no opportunities for interaction or feedback. The standard model attempts to make active use of the Web's technology by allowing a significant degree of communication and interaction between students and staff, including through a subject home page, electronic copies of the printed materials dispatched to students before the semester, lecture slides in Powerpoint format, additional notes arising from on-campus lectures and tutorials, copies of past examinations, and links to the electronic mailing list for the subject. The evolutionary model attempts to address several key issues not addressed in the standard model by allowing the exact method of a course's delivery to evolve from semester to semester, based on identified strengths and weaknesses and weekly anonymous feedback from students. The radical model dispenses with lectures entirely. Instead, students are assigned to groups and learn by interacting among themselves and using existing Web-based resources, with academic staff members providing guidance as and when required.
