It has been reported that teachers are facing more and more abuse on social media.
A teachers union known as the NASUWT said sexist, racist and homophobic remarks were being used by pupils against school staff, as well as offensive comments about appearance.
It added there were also examples of parents being abusive on social media and around 60% of 1,500 teachers questioned in a poll said they had faced abuse, compared with 21% last year.
Of those who had been subject to abuse, nearly half said the remarks were posted by pupils. 40% said they were put up by parents and 12% said both parents and pupils were responsible.
The poll revealed that almost two thirds said pupils had posted insulting comments, while just over a third said students had taken photos or videos without consent.
A third received remarks about their performance as a teacher, 9% had faced allegations from pupils about inappropriate behaviour and 8% had been subject to threatening behaviour.
The teachers poll found more than half of pupils responsible for leaving threatening remarks were aged between 14 and 16 and 38% were aged between just 11 and 14.
