We report on the establishment of communities of practice at four Australian institutions and evaluate their effectiveness and durability as a means of building staff and institutional capacity for interdisciplinary teaching. A community of practice approach is a potentially valuable methodology for overcoming dynamics of fragmentation, isolation and competition within universities. The communities we established were anchored by a shared focus on the topic of climate change and they worked collaboratively to build relationships of trust and reciprocity between teachers in a wide range of disciplines. The aim of each community was to improve the teaching of climate change through enabling members to integrate diverse disciplinary perspectives, to teach collaboratively, to promote innovation through exchange and to demonstrate leadership within their institutions. The key factors that made our communities effective and durable are: (1) designation of two leadership roles, activator and facilitator, (2) provision for institutional autonomy in domesticating the model to fit local circumstances and (3) a pragmatic emphasis on opportunities for teaching innovation and leadership within existing administrative structures, teaching programs and workloads. We conclude that suitably designed and resourced communities of practice are a viable means of improving interdisciplinary teaching of complex problems by facilitating both staff development and institutional learning.

Purpose-Interdisciplinary approaches to climate change teaching are well justified and arise from the complexity of climate change challenges and the integrated problem-solving responses they demand. These approaches require academic teachers to collaborate across disciplines. Yet, the fragmentation typical of universities impedes collaborative teaching practice. This paper aims to report on the outcomes of a distributed leadership project in four Australian universities aimed at enhancing interdisciplinary climate change teaching. Design/methodology/approach-Communities of teaching practice were established at four Australian universities with participants drawn from a wide range of disciplines. The establishment and operation of these communities relied on a distributed leadership methodology which facilitates acts of initiative, innovation, vision and courage through group interaction rather than through designated hierarchical roles. Findings-Each community of practice found the distributed leadership approach overcame barriers to interdisciplinary climate change teaching. Cultivating distributed leadership enabled community members to engage in peer-led professional learning, collaborative curriculum and pedagogical development, and to facilitate wider institutional change. The detailed outcomes achieved by each community were tailored to their specific institutional context. They included the transformation of climate change curriculum, professional development in interdisciplinary pedagogy, innovation in student-led learning activities, and participation in institutional decision-making related to curriculum reform. Originality/value-Collaborative, non-traditional leadership practices have attracted little attention in research about sustainability education in university curricula. This paper demonstrates that the distributed leadership model for sustainability education reported here is effective in building capacity for interdisciplinary climate change teaching within disciplines. The model is flexible enough for a variety of institutional settings.
