Leticia Lowery, 39, is a former teacher and private tutor, deputies said.
The parents of the 15-year-old found the videos and photos on the victim's phone, authorities said.
When Lowery was interviewed, she told authorities that she had talked with the teen, but denied any sexual advances.
Investigators found the photos and videos that were sent from Lowery's phone to the victim's phone, according to authorities.
Lowery posted a $10,000 bond. She is due in court on Friday.
