I have always been curious as to why there seems to be more language arts teachers involved in technology, particularly the interenet. My current theory is that as teachers of reading a writing we have been living in virtual worlds for a majority of our lives.
I use to joke that going to movies and watching tv was professional development, but I was always half serious. Both of these media are just different forms of literature. So it is only natural that Language Arts teachers should be among the first to take of residence and create content on the web.
I have to admit that I haven't searched and that all of my evidence is anecdotal, but there seems to be a lack of math content on the web. Most of the math teachers I know don't use technology for anything other than excercise drills. I know that thousands of math teachers are screaming about this statement, but I bet there are far less math teachers reading this than English teachers.
Most of the science content I have seen is just virtual representations of real world phenomenom. This is not much of a problem. Science is the study of the world around us. I would no more expect them to study the internet than I would have them study fluctuations in gravity in Charles Dickens Tale of Two Cities.
As for history teachers, their presence on the web nearly equals that of language arts teachers. Of course the only difference between the to disciplines is that history is supposedly true.
It would be interesting to see some statistics on this. I could be totally biased and just think that language arts teachers are gods.
