After all, depending on where you live, on average you are likely to be filmed 70 to 75 times a day by a surveillance camera.

Buying our groceries inside a supermarket, walking down a busy street or simply standing in a lift; we are filmed so regularly it is barely noticed, never mind being considered as a breach of our privacy.

But when it comes to filming in classrooms a new debate opens, is this a necessary tool for classroom management or a step too far in controlling our pupils?

Two un-named schools in Britain have been trialling a scheme where teaching staff have been wearing body cameras, similar to that worn by police.

The camera doesn't film all of the time; only if the teacher decides to activate it, and has a two-fold purpose, to act as a deterrent or less positively, to be used as evidence against badly behaved children.

We have come a long way since the days of a teacher being automatically respected by pupils and parents; where the educator was trusted and granted full authority to teach in the way they thought best, with no questions asked.

Thankfully, we have transformed into a less deferential society where teachers now have to earn the respect of students, which in my opinion can only be a good thing, as an abuse of power should never be tolerated.

But has the pendulum swung too far; is an educator's word not enough and needs to be backed up by video confirmation?

Is the only thing stopping an outbreak of violence in the classroom the fear that it will be recorded and used in evidence?

British education newspaper, the Times Educational Supplement, surveyed 600 teachers and found that just over a third would be prepared to wear a body camera.

This group of teachers cited the need to monitor and gather evidence of student behaviour as the main reason why they would wear the camera, which would be worn on the lapel of a jacket, while other reasons included improving teaching and for keeping teachers and pupils safe.

Those opposed cited privacy and the feeling of being spied upon by management.

The safety aspect is a strong recommendation for the wearing of cameras. The number of assaults on teachers and students in the classroom and generally disruptive behaviour is at an all-time high.

In one Scottish region, recorded assaults on teachers rose by 900 per cent during last year alone.

Surely being captured on film would make an angry pupil think twice before lashing out at another pupil or member of teaching staff, as the repercussions would be much greater when the evidence could not be questioned?

Perhaps understandably some parents today are unwilling to believe that their offspring could ever do anything wrong and being shown filmed evidence of their child's poor behaviour would help the parent accept that a transgression had occurred and would now have to be dealt with.

Police officers have found that wearing body cameras has recreated the traditional position of authority with suspects altering their behaviour due to the presence of a camera as they don't want to get into trouble.

A study found that complaints against police officers in the UK and USA fell by 93 per cent over the space of a year when the officer was wearing a body camera.

This was not only because the member of the public altered their behaviour, but because the police officer did, too.

This would also have a positive effect on the conduct of teaching staff who would eradicate the occasions when their own standards slipped if they knew they were being recorded for posterity.

I often wonder how a misbehaving pupil or class would respond if they could watch a play back of their actions; surely seeing how ridiculous they were acting would jolt them back into line as they would feel embarrassed.

On the other hand, there is a possibility the camera might act as an encouragement more than a deterrent for some students. A search for 'classroom fights' on YouTube brings up 173,000 results including titles such as 'Student Attacks Teacher Compilation'.

A number of these fights are not spontaneous incidents but are planned and recorded with everything stage managed by the assailants in order to get a little bit of instant fame and kudos from their classmates.

Knowing that their misdemeanours would be filmed by the teacher for a whole new audience; might our notoriety-hungry students not provoke an event?

Another issue for teachers is that the footage might be used for teacher monitoring through the backdoor. Any mistakes caught on camera could be used to build a case against a teacher that the management wanted rid of.

My greatest sadness about the proposed introduction of body cameras in the classroom is the end of trust, of a neutral space where pupils can make mistakes, lose their tempers or act out inappropriately but where these misdemeanours will be dealt with by the classroom teacher rather than where the evidence will be poured over by senior management within the school before the pupil is dealt with appropriately.

The camera on a teacher's jacket would create a barrier between the teacher and their class almost as large as going into the classroom wearing a stab proof vest, making them more like a police officer rather than someone there to help and support.

How can pupils trust us if we record everything they say or do?

Furthermore, there would have to be robust guidelines about what would happen to the information that had been gathered.

In our modern world of technological leaks, I can imagine an audience for 'funny things pupils have done in the classroom' films escaping out of education authorities, so exposing these kids to ridicule and shaming, and it is for this reason I would be thoroughly opposed to wearing a camera.
