Abstract
Business case studies have been a standard pedagogical tool in technical communication classrooms. However, the expansion of engineering practice-including the design and implementation of appropriate technology in the developing world-suggests the need to complement such studies. This paper analyzes three business and three humanitarian case studies. It highlights the complexities of audience and context that distinguish the humanitarian case studies, and it argues that incorporating humanitarian cases into technical communication courses would promote higher levels of learning, student engagement, and the global citizenship that will be requisite for all engineers in the twenty-first century.
