NEW YORK — A Baltimore public school teacher is no longer employed after a cellphone video showed her berating minority students with abusive language that included a racial slur, the school district said Thursday.

The teacher, who was not named in the statement from the Baltimore City Public Schools, was recorded Tuesday disciplining a student in her middle-school science class at Harlem Park Elementary/Middle School. After she ejected the student from the room, she turned to the other students who remained, raised her voice, and said she was going to give them all zeros for not doing their work.

The teacher, who is white, then called the students “idiots’’ and asked them if they wanted to get an education or to be someone “who is gonna get shot,’’ using a common racial slur.

On Thursday, the school authorities said in the statement that the teacher had “engaged in verbally abusive behavior and made racially charged comments directed at students. The teacher involved in the incident is no longer employed by city schools.’’

An e-mail seeking information, including the name of the teacher and what she had told the authorities about the episode, was not answered immediately by the city schools.

The Baltimore Teachers Union said in a statement that it “condemns the language used by the teacher.’’ A spokesman for the union, Ray Baker, declined by telephone to answer further questions.

But Sonja Brookins Santelises, chief executive officer of the school district, said in a phone interview that the woman was an eighth-grade science teacher in her second year.
