This article argues for a social perspective of the new technical communication service course, a conclusion supported by several premises: the technical communication profession wants and needs accountability, accountability is demonstrated by evaluation, assessment requires that we define literacy, evaluating technical communication literacy requires portfolio evaluation, portfolio assessment supports the social perspective of learning, and the social construction concepts imply teaching strategies. The argument proceeds from a case study that demonstrates reliability, stability, and validity in its technical communication service course assessment, tasks, and instructor community. This article demonstrates that portfolios can help us both conceptualize and evaluate the new technical communication service course.

Assessing the efficacy of technical communication service courses is a complex task, yet it is a task that service course providers should embrace as an opportunity to learn more about student and faculty needs and to update and improve curricula. This assessment has become more immediate for many educators because of ABET 2000 (Accreditation Board for Engineering and Technology), a comprehensive revamping of the way engineering programs are accredited. ABET 2000 criteria require that engineering programs provide evidence of the efficacy of all instruction, including communication. When the new ABET criteria were released, we had already begun a comprehensive evaluation of not only our service courses but also the total writing experience of engineering students at the University of Washington. This paper gives a theoretical rationale for a portfolio evaluation project and describes a directly applicable structure and procedure for such a project.

This article presents a rationale and method for introducing a hypertext authoring assignment in a professional writing course in computer‐aided publishing. We define the technology and its relations to print. We then describe a rhetorically centered pedagogy that incorporates portfolio assessment, collaborative authoring, and real world projects for teaching hypertext within the context of situated problem‐solving theory.
