When Devon Treharne was a high school student in upstate New York, in love with reading and writing, she didn’t apply to be on the staff of her school’s newspaper. “I was intimidated,” said Ms. Treharne, who teaches high school English and a journalism class at the Shelter Island School, as well as being adviser to the school’s newspaper, The Inlet. “The paper had won all kinds of awards,” she said, and she didn’t think she could measure up. “I regret it now.” She remembered that, when she helped revive the Shelter Island school paper nine years ago with former School Superintendent Michael Hynes, she actively recruited students she thought would flourish in student journalism.
