Elementary Children accesing adult sites

Hello all,

Has anyone else run into this?  My son is 9 and he told me of students
doing
this in his classroom and library.  I told the school and it was
happening.
The response from the school department was that they use filter software
which catches most of it but some does get through and it is really the
children's fault for going to those sites.  Having used reasonable efforts
"the filter" they have done all they are required too and that is that.  I
for one do not think the internet has any real educational benefit for
elementary school and am even more upset that the children are accessing
****ography on it, the school department knows and is unwilling to take
the
real steps needed to stop it.

Just so you know I am not anti technology, that is what I do for a living,
I
just think elementary school does not need it.

I told the school department they need to develop a list of approved sites
and block all others, not use a filter to block some sites and allow all
others.  This is inherently safer and is how I let my son use the internet
at home, with me on the couch watching the screen.

Please let me know if you have has similar situations come up.

Thank you,

Paul
