MADELINE J. Marx, 23, has held her teacher qualifications for little more than a year.
She's now been arrested and bailed on charges of engaging in sex acts with at least two of her young male students.
Ms Marx, who has been acting as a substitute teacher for the 11th grade at Kettering Fairmont High School, was arrested on Wednesday and formally charged with sexual battery against a 16 and 17 year old.
The whistle was blown by a student who became concerned after hearing lurid schoolyard gossip, and took the tale to the principal.
"We became aware [Marx] was possibly involved with inappropriate activities with a juvenile," Kettering Superintendent Scott Inskeep said. "When we become aware of them then we will remove those people and not have them around our students."
Police were called to investigate the matter.
Video has been released of the blonde teacher being led away by police in handcuffs.
Court documents reveal Marx has admitted to sending nude pictures through social media services such as Snapchat and Instagram to at least one of the students.
One student, aged 17, claimed she perform oral sex on him while in the car park of a local department store.
Another student, 16, says they had intercourse while in the parking lot of an apartment complex.
Marx, of Brooksville, has been released from Montgobery County Jail on the condition she lives with her father at his home.
She graduated from the nearby Chaminade Julienne Catholic High School in 2012, and gained a four-year licence to teach K-12 (high school) in 2016.
Montgomery County Prosecutor Matt Heck Jr said: "Teachers are entrusted with the responsibility of educating children who are becoming young adults. This defendant took advantage of her position and developing a sexual relationship with minor students."
