"Over the past couple of years," she says, "since Miley Cyrus took the stage 'twerking' at the 2013 MTV Video Music Awards, our students' dancing behavior has crossed the line of what we can condone as appropriate behavior at a school."

"Students do not face one another or remain with the same person for the length of the song. If you haven't seen twerking, I would encourage you to research this online."
