I've talked to a couple of contributors on English Wikinews and we'd really love to engage more with high school and university courses. We just lack the people power to do the outreach to attract them at the moment. Currently, David Blackall at the University of Wollongong has a class using the Wikinews as part of coursework. He made a video about this available at
