Intermediate Interdisciplinary Writing for the Natural Sciences is linked with BIOL180: Introductory Biology. Although the two courses complement each other, they have distinct goals, activities, and assessments. Our focus in ENGL199C is the development of scientific literacy through reading and writing: (1) how does writing contribute to our understanding of the natural world, and (2) how can we write effectively in the sciences, as well as in other disciplines? We address these questions as we read, carefully re-read and discussbioscience writing and commit our responses to writing. We use a process of annotation, paraphrase, and outlining of research questions, experimental methods, and findings to examine the significance of the science writing we read. As we compose and revise our own draft responses, we place special emphasis on the purposes different types of science writing serve in framing scientific questions, and in reporting new science knowledge and debate. Namely, through our writing we seek to understand the way any one scientific study enters into conversation with other studies in an area of research.
