The teacher has been put "on leave" and has had this problem before in his classroom.
DALLAS — Michael Hinojosa, the superintendent of the Dallas Independent School District, is publicly speaking out for the first time after a series of videos aired on News 8 showing fights inside Seagoville High School.
"Obviously, it's a very disturbing video," Hinojosa said. "That's unacceptable behavior in any of our classrooms. I'm very disturbed about the actions and the incidents that occurred in the classroom."
The superintendent said he was angered by the videos that show students punching other teenagers inside a classroom on two separate occasions.
Both fights happened in the classroom of math teacher Lindale Muse.
In one video clip, a shirtless student removes his shorts, apparently preparing for a fight. As the students square off, the camera pans to show Muse, 54, standing behind a podium and watching.
"We are focusing on that one classroom at this time," Hinojosa said.
The superintendent has demanded an expedited investigation, while Muse, 54, remains on extended administrative leave.
When reached by phone Tuesday, the math teacher denied that he allowed fighting in his class.
"Teachers are not responsible for breaking up fights," Muse said. "It's under investigation. I can't comment on it."
The superintendent would not say how long the district's investigation would last.
"We always follow due process," Hinojosa said. "Every employee has the opportunity to be heard."
