A science teacher who had an affair with a 15-year-old pupil has been jailed for 18 months.
Michael Pooley, 35, dated the teenager for four months, taking her on day trips and to a hotel, until her parents found out what was going on.
Judge Alan Goldsack QC said he hoped Pooley's sentence acted as a warning to any others in his profession 'thinking of behaving in this way'.
He told him: "Parents are entitled to expect when their children leave home to go to school that they are going to be safe and teachers will protect rather than abuse them."
The court heard how a mutual relationship developed between Pooley and a girl, who is now 17 and cannot be named.
The girl had a crush on the teacher and they began to see each other out of school, eventually going on trips together and staying in a hotel.
Sheffield Crown Court heard how the pair communicated using Facebook and Pooley even set up two fake accounts on the social media site so the girl's parents would not spot he was talking to their daughter.
Judge Goldsack told Pooley: "You had regular contact by Facebook - a social media which certainly those that sit in court regard as more harmful than helpful."
The court heard that despite the defendant admitting touching the girl sexually, there was no full sex between them. He told the girl he wanted to wait until she was 16-years-old.
Pooley, of Potternewton, Leeds, admitted seven counts of sexual activity with a child and two counts of child abduction at a previous hearing.
He was jailed for 18 months, ordered to sign the Sex Offenders Register and was banned from working with children indefinitely.
