All great inventions have applications for evil as well as good; you can't have one without the other, but the technological society has brought in its wake an unimagined nightmare for schools.
On the plus side, pupils have at their fingertips a wonderful world of information and learning, but it still remains true that technology in the wrong hands can make life nigh on impossible for pupils and teachers alike.
In the classrooms of 50 years ago, it was an altogether more innocent age when teachers didn't generally have more to fear than ink-bombs, pieces of blotting paper that could be dipped in ink and thrown at the teacher when he turned to write on the blackboard, or drawing pins placed on his chair - all definitely low key.
Anyway, naughty children had their parents to contend with, not only their teachers. Tell your dad you'd been caned or given detention for misbehaviour and you were more than likely to get another cuff from him, as you "must have deserved it".
A colleague of mine, who taught mining apprentices more than 30 years ago, was once driven to fury so much by one boy as to smite him over the head with his own T square.
Terrified of the sack and of the boy's threat to "tell my dad," he lived in dread for a week until he took the class again and found the boy, not in his usual place at the front of the class, but right at the back, wearing his miner's helmet.
Let's face it, from Will Hay to Jimmy Edwards, teachers have always been figures of fun, fair game for playing up, Aunt Sallies for children to try out their insolence and practical jokes on. This, I suppose, explains the age-old popularity of school stories, from Billy Bunter, through Enid Blyton to Harry Potter.
Now, however, it seems that modern technology has given a sinister new twist which has become deadly serious, with vindictive pupils using technology to get teachers sacked. It has long been thought that teachers are fair game for verbal and physical abuse, fireworks put through letterboxes and obscene phone calls, but things have recently taken a much worse turn.
Only recently, it came to light that in several schools, children have been mocking up pictures on their mobile phones, purporting to show teachers assaulting pupils, with the aim, one assumes, of getting the teacher sacked. Of course, any move by schools to ban the use of mobile phones in schools will be vehemently opposed by parents.
Not content with this type of offence to try to ruin teachers' careers, we have only in the last couple of weeks heard the case of two boys in a school in Redditch who duped a teacher into telling them his computer password and then used it to download pornography, which they then distributed to other pupils.
Only when a pupil took the material to the head teacher and a rigorous inquiry was carried out did it become clear in which class the material was downloaded (luckily the teacher whose password was used was teaching in another room at the time) and the boys responsible confessed.
It might be argued that they didn't realise the possible consequences of their actions, but it remains a fact that the teacher concerned might well have lost both his career and his liberty because of them.
