BY DAY, Christopher Paslay teaches The Crucible and Thoreau's Walden to juniors at Swenson Arts and Technology High School.
By night, the 39-year-old teacher-turned-blogger maintains a website, Chalk and Talk, that gives public-school teachers a voice.
For Paslay, it was the advent of the No Child Left Behind reform model - the idea of holding schools to standards judged by test scores - that triggered his advocacy on behalf of his fellow teachers.
"The disparaging of public-school teachers all the time got me a little upset," explained Paslay, who's taught English at Swenson, in Northeast Philadelphia, for 15 years. "They're doing good things, and you don't hear much about it."
