Computer lab classroom management

In my computer applications in ESL teaching,while talking about classroom management in computer lab, Mark Miller, our teacher, mentioned that it is better to help the student develop their sense of responsability rather that simply control and stop them from having access to mature material or simply to programs disturbing them from doing their work. I really found this approach interesting. Most of the time, teachers simply control the students and block access to certain sites on the internet. If this may work for a certain time, students eventually find a way around the blocking programs. Also, we must realise that the teachers won't always be there to watch and control the students.
When we try to responsabilise the students, we invest on a much longer term. Even though it is much difficult to control the students on short term and that it demands more time with the students, we are investing on their future and making them better human beings. We are teaching them the importance of responsability and of self-control. This will be useful in all their life, in their post-secondary studies and will help them with their work ethics.
