Abstract
The use of writing as a means of assisting students to learn and of assessing their understanding in an introductory science course intended primarily as a terminal course for non-science majors is considered in the context of a discussion of cognitive development. We suggest that, par-ticularly where students are asked to justify their understanding by refer-ring to concrete evidence, writing samples are a sensitive indicator of cognitive position. We demonstrate this with examples of four different types of writing used in our course: short answer exam questions, exam essays, take-home essays which may be revised, and informal journal writing. The information gained from writing assignments can be useful as feedback to an instructor regarding (a) an individual students assump-tions about what can be known in science and what form this knowledge takes, (b) what individuals and the class as a whole are prepared to under-stand, and (c) in what ways particular subject material is likely to be misun-derstood. We conclude that these different probes can reveal different aspects of development, and that the use of any of them requires attentive reading by the instructor.
