Nice post at Edublog Insights dealing with the ups & downs of weblogs in education.
I guess there’s an important point left to say and it deals with learning by teaching: it’s surely a very good way to learn and know what you learnt (or what you just did not) to test it by trying to explain it to others. It’s no doubt the most interactive and the most proactive way of learning.
And I find this specially relevant in communities where educators are scarce and students have to learn quickly and take the role of the trainer to share his knowledge and help the community develop.
Like Nancy, I neither believe blogging will save the world, but sharing is a good way to start. And a blog, over anything else, is a sharing tool, no doubt of it.
