The Winter Park-area man accused of having sex with two students when he taught at Lyman High School waived his appearance at an arraignment Tuesday and instead submitted a written not-guilty plea.
Scott Kimbrough, a 39-year-old math teacher, was arrested last month on child-sex-abuse charges involving a 17-year-old female student.
He was rearrested a few days later when another female student told police she had sex with Kimbrough twice at his house in 2011 when she was 15.
Tuesday's arraignment was in relation to his second arrest.
The Seminole County School Board voted to dismiss Kimbrough earlier this month.
Kimbrough did not contest the dismissal recommended by Superintendent Walt Griffin.
The school district also forwarded a complaint to the state Department of Education, which could strip Kimbrough of his teaching certificate, school district spokesman John Reichert said.
Kimbrough, who has been with Seminole schools for 13 years, taught analysis and algebra classes in addition to sponsoring the anime club and Mu Alpha Theta, a mathematics honors society.
The investigation was initiated after teachers and students told Longwood police they saw what appeared to be inappropriate conduct between Kimbrough and the first teen.
The second girl told the Seminole County Sheriff's Office that she and Kimbrough had sex twice at his house near in Winter Park in 2011 when she was 15, a report states.
She also said she sent him nude photos of herself.
The first girl also told authorities that she and Kimbrough also had sex at his home. Those encounters happened at least three times in the three months before his first arrest, investigators said.
