Police say the 37-year-old teacher performed oral sex on a male student in a classroom during school hours.

Police say Gurecki-Haskins also sent text messages and e-mails to two 16-year-old male students. Court papers obtained by CBS affiliate WROC say the messages "encouraged a sexual relationship."

Gurecki-Haskins, a teacher at Canandaigua Academy since 1995, turned herself in on Monday.

She pleaded not guilty to a felony count of disseminating indecent material to a minor and three misdemeanor counts of official misconduct and endangering the welfare of a child. Officials say more charges could be filed.

Police have been investigating these accusations since early April, according to WROC.

Gurecki-Haskins has been released on her own recognizance.
