LAND O' LAKES, Fla. -- A Florida science teacher has been suspended for running a signal jammer to prevent his students from using their cellphones in class.
School board members in Pasco County approved Dean Liptak's five-day, unpaid suspension on Tuesday. Liptak didn't contest the decision.
Officials say Liptak activated the jammer in his Fivay High School classroom from March 31 through April 2.
He later told a school district investigator that he never intended to cause problems. He said he thought the jammers were allowed as long as they were not intended for malicious purposes.
