An argument over Adam and Eve between a city-paid teacher and third-graders at a private Muslim school has landed the instructor in pedagogical purgatory, The Post has learned.

English teacher Nina Kossman committed the sin of “telling the truth,” she said of her expulsion from the Razi School in Woodside, Queens, which uses taxpayer-funded city Department of Education teachers in a federally-mandated program for poor kids.

Kossman infuriated parents by telling their children that Adam is “not real.” She noted that Judaism, Christianity and Islam share the myth, thinking it would “help build up tolerance” for other faiths. She also inadvertently showed kids a classical painting of the first couple as imagined in the Garden of Eden — nude.

A group of angry parents showed up at the school the next day to complain that she “discussed Jews with them and showed them pictures of naked people,” Kossman said Imani Al-Amin, an assistant to the principal, told her.

Kossman replied, “It’s just a story, a myth. It’s not real.”

The boy objected: “Adam is not a story! He is real!”

But Kossman persisted, “The story of Adam and Eve belongs to three religions — first Judaism, then Christianity, then Islam.”

When some kids said they didn’t believe it, Kossman opened her laptop and called up the Wikipedia page on Adam and Eve. Up popped the famous painting by 17th-Century artist Paul Rubens of nude Adam and Eve.

“Ooh! Naked people!” kids cried. “We’re not allowed to look at naked people!”
