WPost: More teachers are having sex with their students. Here’s how schools can stop them.

A 14-year-old student in Florida wrote his cellphone number on a classroom chalkboard because he wanted a classmate he liked to call him. The student indeed was contacted – not by the girl but allegedly by his 32-year-old teacher. Within days, police said, the two were involved in a sexual relationship.
In Pennsylvania, a 33-year-old teacher approached a 17-year-old student at a school dance and began flirting with him, police said. The married teacher then sent the student sexual text messages and photos, along with a video of herself performing lewd acts, according to news reports. The relationship escalated, and the teacher pleaded guilty last month to institutional sexual assault.
