Designing Like an Institution: Systems Thinking, Design Thinking, and Visual Grammars in Sustainability Education

Sustainability education increasingly centers on systems and design thinking to address complex socio-environmental challenges. While these approaches enhance reflexivity, interdisciplinarity, and problem-solving capacity, this paper argues that they also translate complex problems into forms that institutions can recognize, act on, and bring to closure. Drawing on institutional theory and visual semiotics, this paper uses grammar in a structural sense to examine how sustainability education organizes perception, responsibility, and action. The analysis focuses on recurring pedagogical images—including the iceberg model, feedback loops, empathy maps, and the double diamond—and is informed by prior analyses of visual representations. Rather than treating these images as representations, this paper analyzes them as pedagogical infrastructures that stabilize recurring grammars of actionability in the sustainability field. These grammars translate disagreement, complexity, uncertainty, causality, and moral distance into forms that are legible, actionable, and provisionally closable within institutional contexts. While this alignment enables coordination and responsiveness, it also narrows the scope of responsibility by privileging synthesis, adaptation, and iteration over redistribution, obligation, and structural transformation. For educators, this framework offers a way to teach students not only to use systems and design tools but also to reflect on what it means to be an agent of change while institutionally embedded.
