The strong argument about techology in schools has always been about the money....I recently heard that distribution of funds within the school is metered out by the Principal. Therefore, it would stand to reason that the Principal should consider the importance of technology and making that accessible to all students.
I have teenagers who signed an IT Contract wherein they agreed to surf the net responsibly. All students and parents sign the contract although not all students honour their agreement. It is the monitoring of the internet that comes into scrutiny and in a large classroom it is very difficult to overlook all the computers.
In saying that....I agree that there should be a greater focus on having technologies of all kinds available to students....we live in a technological world surely we need to prepare them for it??? Again, the challenge is monitoring the content.
