Over a long career in academia, I have helped many research students formulate and chase down their puzzles into a thesis. For me supervision of graduate students is the most important and certainly the most rewarding aspect of a career in academia. The project of my first ever research student (in the 1980s) inquired into science teaching in African primary school classrooms. The projects of my most recent graduating students concerned among other topics: sociotechnologies of language work; the delivery of human services in remote Indigenous settings; and knowledge and politics in Australian heritage work.
