I used a tool recently which counts the number of words I’ve posted on my blog. I’ve written a total of 339,254 words on my blog (as posts and comments), and other people have written a total of 111,474 words as comments on my posts.
This level of engagement and thinking has got to make a difference on my understanding of education, and at least indirectly on my skill as a teacher. When I say that blogging has made me a better teacher, I mean it.
