O’Brien, Liam. “Building a Scaffolding for Student Writing across the Disciplines in Communication Studies." Writing across the Curriculum. Ed. Mary T. Segall, and Robert A. Smart. Portsmouth, NH: Boynton/Cook, 2005. 18-27.
Similar to William Keep (see previous post), Liam O'Brien notes that having students write a journal can be a good way to improve their writing without instructors having to grade every word (20-21). In general, students found writing useful for their education, even in courses not often associated with writing such as biology (see page 39 in Segall and Smart) and math (see page 148 in Segall and Smart). But merely including a paper in a course is not enough to achieve this success.
