I propose Multimodal Critical Discourse Analysis (MCDA) as an approach for understanding the discursive and material implications of technical documents in distant sites. I provide a historical vignette of MCDA and exemplify how technical and professional communication (TPC) researchers can critically engage with distant sites through MCDA by analyzing materials about GhanaPostGPS, a geolocation technology. I conclude by discussing limitations of MCDA – access to archives – and propose the creation of crowdsourced technical documentation archives.

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.
