A Schofield Middle School teacher embroiled in a controversy after reportedly reading to his students from a science fiction book that one parent described as "pornographic" will not face criminal charges, police said.Aiken Public Safety officials said the teacher did not do anything criminal, and the police investigation is closed.At press time Tuesday, they did not give further details.The Aiken County School District's internal investigation remains under way, Associate Superintendent Dr. Cecelia Hewett said Tuesday.On March 12, the teacher was placed on administrative leave while police and school officials investigated whether he breached school policy or the law when he read from three books, among them "Ender's Game" by Orson Scott Card, which became the focus of the probe when a 14-year-old student's mother complained about the subject matter of the book.She went to school officials on Friday, March 9, and then to Aiken Public Safety the following Monday.In addition to the Card novel, which has won several science fiction awards and is listed on numerous children's literary review websites as appropriate for children 12 and older, the teacher read excerpts from an Agatha Christie novel and a young adult novel set in the Old West, officials said.The teacher reportedly selected the books, but may have not followed school policy that would require the books first be reviewed.Joy Shealy, school district academic officer for middle schools, said there is a policy that defines steps teachers should to take when presenting supplemental material."One of the things that teachers are supposed to do is preview material for appropriateness for any questions that may come up," Shealy said. "By doing that, we make sure the materials that are presented to students are age- and instructionally-appropriate - all the things that make a good instructional program."School officials said they expect the matter will be resolved quickly.Administrators said the investigation will include whether school staff followed district protocol in a timely manner."Matters that involve personnel considerations are dealt with promptly but must take into account reasonable measures to protect the privacy of students and staff," according to the district administrator's statement.Rob Novit contributed to this article.Karen Daily, a graduate of USC, has been the crime reporter at the Aiken Standard for seven years.

A brilliant young boy, Andrew "Ender" Wiggin lives with his kind but distant parents, his sadistic brother Peter, and the person he loves more than anyone else, his sister Valentine. Peter and Valentine were candidates for the soldier-training program but didn't make the cut--young Ender is the Wiggin drafted to the orbiting Battle School for rigorous military training.Ender's skills make him a leader in school and respected in the Battle Room, where children play at mock battles in zero gravity. Yet growing up in an artificial community of young soldiers, Ender suffers greatly from isolation, rivalry from his peers, pressure from the adult teachers, and an unsettling fear of the alien invaders. His psychological battles include loneliness, fear that he is becoming like the cruel brother he remembers, and fanning the flames of devotion to his beloved sister.Is Ender the general Earth needs?
