Oh yes there is!!
I would only do a disservice to Karl Fisch if I tried to summarize or in any other way tamper with his brilliant post on how he plans to integrate writing into his Algebra class. Go read it now! (But please come back for a moment!)
One of the most powerful things about the post (and to be honest, most of his posts) is how transparent he is in his thinking. He admits the roadblocks to implementing his plan, he lays out his plan with some links to his other work and references the work of others, and he acknowledges that he may not get to all parts of his plan.
But he uses his blog to publically announce his plan and ask for feedback. That is one example of what blogging is all about! Did you start your blog yet?
