This research embedded in the National Study of Writing Instruction examines higher- and lower-achieving adolescents' stances toward content-area writing through a qualitative discourse analysis of interviews with 40 students in California, Kentucky, New York, and Texas secondary schools. The study asked: (1) How do students' stances toward writing compare in general and across disciplines? (2) How do stances compare among middle and high school students and among students with different achievement histories? Results suggest that adolescents generally hold positive attitudes toward writing that allows for the expression of subjective stances, which they report is more commonly assigned in English language arts classrooms. Implications for the adoption of new US standards for disciplinary writing are discussed.
