AB: Writing activities can improve student understanding of scientific content and processes. We have studied student writing to identify the challenges that students face in composing scientific arguments and to clarify features that constitute quality in scientific writing. We have applied argumentation analysis for the assessment of students' use of evidence in a general education oceanography course. Argumentation analysis refers to the systematic examination of ways that conclusions are supported with evidence. The student writers were supported by an interactive CD-ROM, "Our Dynamic Planet," which provided students with "point and click" access to real earth data and allowed them to solve many problems associated with plate tectonics. Plate boundary types (using quakes, volcanoes, elevation profiles, and heat flow) and plate motion can be determined (seafloor age, island ages/hot spots) with this technology. First, we discuss the structure of scientific argument and how this structure can be made accessible to undergraduate students. Second, we present examples of argumentation analysis applied to student writing. These examples demonstrate how use of large scale geological data sets can be used to support student writing. Third, we present results from a series of studies to show ways that students adhere to the genre conventions of geological writing through use of theoretical claims, multiple lines of evidence, and cohesive terms. These results, combined with our evidence-based orientation to instruction, formed the basis for modifications in the course instruction. These instructional modifications include providing detailed examples of data based observations and interpretations, heuristics for assessing other students' arguments, and quick write exercises with similar but simplified writing tasks.
