In 1984 the Human Biology program at Stanford University launched a writing across-the-curriculum project with a year-long writing-intensive introductory class. The immediate objectives were to (1) develop students' writing fluency by demanding more writing, (2) improve the quality of all student writing by increasing attention to the writing process and to written work, and (3) help students understand that writing is a valuable way to analyze and deepen knowledge of course content. During the first year the program secured space for a writing resource center where the writing assistants could confer with students, teaching assistants, and faculty. Ways to develop students' speaking capabilities were also explored, and the program focused on developing a learning resource center. The Human Biology program also purchased video equipment to use in making pilot training tapes. The program has documented evidence that it is making a difference in student performance on essay examinations and in written assignments. Because Human Biology is an interdisciplinary program, it exemplifies how writing can be integrated across the curriculum. (AEW)
