The theme course has not held a distinct place in scholarship, despite being a longstanding practice in the field; meanwhile, it has come under scrutiny in teaching for transfer (TFT) scholarship, which perceives the practice as conflicting with writing-centered approaches. In contrast, scholarship on theme courses suggests that a resilient motive for selecting and implementing a theme is to support writing as subject matter. A survey of current practice confirms this motive. If the theme course is not in conflict with disciplinary values, and instead a proponent of them, then the practice should be studied with more intent as a peer or supporting practice to other writing-centered approaches. This article diffuses tensions between TFT and the theme course to reposition the theme course as a method for teaching writing as subject matter.
