One of the best things about no longer being a teacher is that I don't have to mark and I don't spend the time before the coursework uplift Googling chunks of 150 essays to make sure that the cherubs haven't plagiarised.
I had one mother raising hell because the classroom teacher had voiced the opinion that the essay wasn't the kid's own work. The writing was clearly far too good, compared with their normal output. In addition, no sources were listed. (The rules stated that candidates either had to list their sources or to sign a statement saying that none had been used. This was clearly a topic that had to be researched - animal testing.)
The mother informed me that she took exception to the accusation and that it was definitely the kid's work because Mum's laptop had been used and Mum had been present the entire time that the kid had been typing away.
After the meeting with the parent I spent bloody hours at home Googling and highlighting a photocopy of the coursework.
The kid had downloaded three different articles from the internet and had then copied and pasted one sentence from each essay in turn, all the way through the essay. (I used three different coloured highlighters.)
Two words had been changed: one of the plagiarised articles had orignally been about testing make-up on animals. The kid had twice deleted "make-up" and had typed "drugs".
I happen to be exceptionally petty, so I mailed the mother a copy of the highlighted essay together with links to the plagiarised sources. I didn't hear another word from her.
As a colleague said, the mother's statement that she'd been with the teenager all the way through was basically an admission of her complicity.
