To the surprise of the 15-year-olds at Bjursås School in Falun in central Sweden their teacher did not get angry when they covered one of the classroom walls in rather detailed doodles of male and female private parts (click here to see a photo if you're not prudish).
Instead Johanna Johansson decided to turn the prank into a sex education lesson. She put together a number of topical questions and stuck them on the wall next to the corresponding drawings, before quizzing her pupils on anatomy, breast cancer and sexually transmitted diseases (STDs).
“The pupils had scribbled on the wall and expected a negative reaction, which they didn't get. I decided to quiz them on these topics instead. It's what interests them, they are teenagers after all,” the science teacher told The Local on Monday.

She put the youngsters through their paces on questions such as “what is mammography” and “what protection should you use to avoid STDs and pregnancy” before they all cleaned up the graffiti together.
“They thought it was really funny and giggled. These are topics we teach anyway – they're part of the curriculum – but this was just a good opportunity to talk about them in a relaxed way,” she said.
The lesson went viral in Sweden on Monday after the school posted pictures of the educational punishment on social media, with overwhelmingly positive reactions.
“Hooray for this smart teacher,” wrote one Twitter user.

It is not the first time Bjursås School is in the spotlight for its unconventional teaching methods. Another move by the school's principal, Tim Guigane, went viral just days ago when he dyed his hair pink in support of a teenager who had worked hard to boost his grades.

“We're a small school and we put a lot of effort into creating good relations with our pupils. There's no point in screaming and shouting at them; we try to turn incidents into something constructive instead,” Johansson told The Local.
