Science communication education is fundamentally concerned with relations between and within communities, cultures and institutions. Through exploration of these relations, it develops understanding of how knowledge is produced, shared and validated. Science communication operates at the boundaries and intersections of disciplines in its professional practice and it analyses them in research and education. At its interdisciplinary best, science communication is a continuing exercise in reflexivity on science and its place in wider intellectual and public culture. From this “premise”, this essay reflects on the “promise” of bringing perspectives from humanities, social sciences and natural sciences to bear on science, the “pleasures” of science communication as “joyously interdisciplinary”, but also on the “problems” in fulfilling the promise and realising the pleasures. It closes with a “proposition” for giving interdisciplinarity a more prominent place in science communication education.

The global problems we face call for universities to prioritise science communication education and training. Here, we describe how we integrated sustainability into a master-level course in science communication through three iterations. By retrospectively analysing our actions and reflections, we demonstrate how and why we progressed from education about sustainability to education for sustainability, and finally education as sustainability. We conclude by discussing our findings, and offering our implications for the teaching and learning of sustainability science communication and of science communication.
