Food memoirs in English teacher Ian Doreian’s 10th-grade class are an extension of another project called “Culture Vulture.” Each term, says the John D. O’Bryant School of Mathematics and Science teacher, students engage in a cultural activity and then write about it in a first-person journal, a sample advertisement, or a third-person-style newspaper article. The activities range from a restaurant review to a museum visit to an author reading. “What I realized is, of course, everybody loves food. Everyone loves writing about their families. So this was the perfect matchup,” says Doreian, 33, a Roxbury resident.
