( CNN ) -- A judge in Tampa , Florida , on Monday sentenced Stephanie Ragusa , a former middle school math teacher , to 10 years in prison for having sex with two underage students in 2008 . `` As parents , we place our trust in teachers to provide a safe environment in which our children can learn , '' Hillsborough County Circuit Judge Chet Tharpe said in handing down the sentence . `` You violated that trust in the worst imaginable way . '' Tharpe also sentenced Ragusa to 15 years of sex offender probation following her prison time . Ragusa , 31 , pleaded guilty in April to three counts of lewd and lascivious battery in a March 2008 case involving a 14-year-old boy , and two counts of having unlawful sex with a minor in an April 2008 case involving a 16-year-old student . Ragusa has been in jail since she was arrested in 2008 leaving one of the victims ' homes . Monday 's sentencing included testimony from the victims ' families , who depicted Ragusa as a sexual predator who caused severe emotional distress for their sons . `` Miss Ragusa maliciously and intently preyed on my son and the other boys , '' said the mother of the 14-year-old victim . `` She had access to their charts as far as their emotional behaviors . ... I feel that she was very conniving ... in picking these boys out and preying on them and using that to manipulate them and seduce them . '' Prosecutor Rita Peters also played a phone conversation between Ragusa and the younger victim that police recorded with the 14-year-old 's consent . In the tape , Ragusa can be heard urging the teen to keep their encounters secret . `` It 's ... one of those things you have to take to the grave , '' Ragusa says on the tape , explaining that sex crimes involving minors have no statute of limitations . In arguing for the maximum sentence , Peters portrayed Ragusa as a `` master manipulator . '' `` She is the one that goes in and looks at their weaknesses , '' Peters said . `` She knows exactly what she has to do to get into their lives . '' In a statement before her sentencing , an emotional Ragusa -- wearing an orange jumpsuit and shackled at her hands and ankles -- expressed remorse for her actions . `` I 'm sincerely sorry for the pain and aggravation I have caused to the victims and their families , '' she said . Her attorney , Robert Herce , asked the judge to sentence her to probation with time served , saying she has spent more time behind bars than other people who have faced similar charges . A psychiatrist for the defense also testified that Ragusa has been diagnosed with bipolar disorder and borderline personality disorder . But Tharpe issued the maximum sentence and did not hold back in his final statement to Ragusa , calling her a `` danger to the children in our community . '' `` You not only have disgraced yourself , your family , but also the teaching profession , '' Tharpe said . `` And one thing that I have gleaned out of this sentencing hearing this afternoon is you 're a very selfish person . '' He added that he remained unconvinced that Ragusa had accepted responsibility in the case . `` You stopped only because you got caught and put in jail , '' Tharpe said . As part of her probation , Ragusa must abide by a mandatory nightly curfew , enroll in an outpatient sex offender treatment program and will not be allowed contact with the victims . She also will not be allowed to live within 1,000 feet of a school , day care , playground , park or any other area where children congregate , nor will she be allowed unsupervised contact with children under age 18 . The defense said after the hearing that it was disappointed with the sentence . `` I was not expecting that harsh of a sentence and I think this case did not warrant that , '' Herce said .
