Student participation in online learning activities is a growing priority for Australian government schools. 'Online projects' have emerged as a new learning form, building on non-computer problem-based learning approaches. This paper reports on a study of online learning projects implemented in classes from year 2 to year 11. The purported benefits of online learning were explored through in-depth case studies of the selected projects. Results of the study are presented, providing a window onto the learning events as each project unfolded and highlighting the achievements of students. The study's findings have significant implications for education systems and teachers, in the design and implementation of online projects as part of an effective learning provision for students. The potential and limitations of an online project approach are placed in the context of online learning developments occurring in New South Wales and Australia.
