At the recent History Extension Development Day I spoke with a number of teachers who were interested in having their small classrooms interact with a wider range of students and I mentioned 'blogging'.
I have got a site up and running at the moment and my students are not far behind. Anyone interested in joining can find my site by going to... http://kandoshistory.edublogs.org
If you are interested in you and your students starting your own blogging site, which I recommend, go to edublogs.org (just google it) and sign up. I have also created a small powerpoint to follow if you need help and my HT has also created a CD all about blogging. My email is debbie.locke@education.nsw.gov.au
