For a 5-year-old Miami student who came home from school with a cut lip from being kicked in the face, the bully wasn't a playground menace -- it was, she alleges, her teacher.
The preschooler's offense? Using the restroom without permission during naptime.
Miami police arrested Head Start teacher Jean Dorvil, 56, on child abuse charges. Miami-Dade Schools Police Sgt. Ivan Silva told ABCNews.com that detectives found during the course of their investigation that Dorvil had allegedly kicked two other students during the school year.
Dorvil's alleged acts were just one of many headlines this year that about teachers accused of dangerous or, at best, wildly inappropriate behavior inside the classroom and out.
Some incidents border on humorous – like the Ohio teacher who reportedly resigned after taking four female students to a male strip club. Others, like the Washington state teacher who was accused of sending a student's feces home in his backpack, appear to be just plain mean.
"I don't understand what some of these people are thinking," said Anthony David Adams, who has made a career out of exposing school wrongdoings by both teachers and students on the Web site DetentionSlip.org.
Adams, who jokingly calls himself the "Perez Hilton for education," told ABCNews.com that he co-founded the site just over a year ago to shed a spotlight on "embarrassing, crazy situations."
While in reality schools are still one of the safest places for children to be and the vast majority of teachers are responsible and dedicated, "some teachers are just not thinking as well as they should," he said.
Francisco Negron, general counsel for the National School Board Association, said that while the group is aware that inappropriate behavior occasionally occurs in America's schools.
"There will always be the case, as in every part of society, where there are a few bad apples," he said. "Those bad apples are not representative of the profession as a whole."
In Miami, the mother of the girl who said she was kicked by her teacher, has hired a lawyer and plans to sue Dorvil and the county-run Head Start pre-school program her daughter attended at the Charles R. Drew Elementary School.
Cynthia Blue declined to speak to ABCNews.com but her lawyer, Greg Durden, said that 5-year-old Mikel has nightmares and is terrified of returning to school.
Durden provided ABCNews.com with a copy of the incident report filled out the day Mikel was allegedly kicked. Signed by Dorvil and an administrator, the report said Mikel was "agitated as usual" and that "apparently she bit or bumped her upper lip."
But Durden said they're lying and that Mikel came home from school that day with blood still on her shirt.
"They didn't even have the decency to clean her up," he said. "They didn't even give her first aid."
Durden said Mikel has not returned to school. He said he and his client are disheartened that Mikel -- an inner city child -- is now terrified of the place where she is supposed to get a foundation for a better life.
"How can some grown man kick a child in the face?" Durden said. "It's horrible."
Sgt. Silva said that, while in police custody, Dorvil admitted to kicking Mikel and the two other children. No one answered the phone at his home.
