The current debate about children accessing Net pornography in schools is part of a wider panic about the dangers of the Internet. School teachers are merely the latest group to be caught up in an irrational reaction to what is probably one of the greatest communications developments since the advent of the printing press. Put in this perspective the idea that students' access to the Internet needs restricting is simply absurd. Teachers do not need to use censorware to help them control unruly children. No amount of porn-blocking software will guarantee that pupils will concentrate on the educational subject rather than playing cards at the back of the class or throwing paper darts.
Teachers are the experts at getting students to acquaint themselves with educational material.
Installing filtering software in schools cannot help teachers to inform and develop their pupils. It can only reinforce the prejudice that teachers don't do their job and propagate the myth that society is better off without the freedom of the Internet.
