With all likelihood, another person, looking perhaps a bit bot-like, will come along and scream back: “Via.Gra! Best prices! Order now!“
This describes the problem many bloggers in educational settings face. At school, a blogging project may last only a few weeks, not enough to gradually build an audience in the same way many 'free range' bloggers do.
In my interviews with teachers using blogging in their teaching, some suggestions where made, e.g. that teachers could heavily advertise student blogs in their own networks. Quite a few student blogs may actually be of interest to, lets say, fellow art teachers or biologists, since they may allow them a glimpse into a colleague's classroom. Another idea was that students could use their own networks to advertise their blogs through other media, such as social networks or Twitter. Even if friends and family may be less interested in expressionism or mammals, they may find it interesting to see how their friends or family members spend their time at school. In the first case, I would expect friendly encouragement as well as feedback on content, in the second case, I do not expect much feedback on content. A third idea was to use the classroom itself as a micro audience. Here, students can be advised on the kind of feedback expected, or can discuss how useful they found the feedback received and how this compares with the feedback they themselves have given.
I'm thinking, though, whether other models may be possible. In the context of language learning, there have been experiments with two classes of students, from different countries, blogging together, e.g. documenting an exchange program. Could such models also be adapted to subject learning? Different student groups mean that each group might have learned content in a slightly different way, may provide different examples or have done different experiments, read different texts, etc. Also, the social dynamics would be very different from what happens during in-class commenting (though I do not claim that they would necessarily be better).
How do you create an audience for your blog? How do you help students do the same?
