I am EXTREMELY fortunate to have a tech department that trusts, yet critiques, our Internet openness. They are not opposed to opening up the filter as long as we understand the "ramifications" of having a website unblocked. We do not block YouTube. We do block MySpace and Facebook. We have also looked into creating different layers of filters for/because of our students. But Mr. Richardson makes a valid point: Locking down your filter can make your students less safe. When they go home, there isn't (usually) a filter, allowing them to access anything and everything. So isn't it in our students' best interest if we teach them about the Internet instead of hiding them from it? This isn't a case of what they don't know won't hurt them. I also love what Mr. Richardson says about how a locked down filter "insults the profession" by blocking teachers out from the same websites as students. It tells me that you don't respect teachers enough to put in the extra time to create layers of filtering.
