To help writing faculty learn the language of discourse communities across campus, we conducted faculty interviews as a first attempt to describe knowledge about disciplinary cultures, specifically with regard to writing. Based on the data received from the interviews about disciplinary definitions and characteristics of good writing and how writing is learned, we advocate (a) awareness: recognizing that the particular beliefs and practices of a discipline may differ from those of other disciplines; (b) knowledge: learning about others' values, particularly regarding the definition and practice of writing; and (c) skills: altering perceptions and even communication strategies based on awareness and knowledge. Our interview data suggest that when writing faculty limit cross-disciplinary discussion to characteristics of good writing only, discipline stereotypes are reinforced, and communication may be restricted. However, when writing faculty discuss learning-to-write strategies with faculty in other disciplines, the results reveal commonalities about writing ideology.
