Evaluating innovation in transdisciplinary sustainability education: TRANSECTS' international learning labs

Evaluative research can advance sustainability education through the learning it can enable, at micro and systems levels. This proposition is explored by examining evaluation practice in a 6-year international programme entitled Transdisciplinary Education Collaboration for Transformations in Sustainability involving universities and biosphere reserves/regions in Germany, South Africa and Canada. A Transdisciplinary International Learning Lab (TILL) was evaluated using a theory-based evaluation approach and interviews, focus groups and questionnaires that yielded qualitative data. Through metareflection, we concluded that our TILL had elements of a Field School, rather than a Learning Lab, and that our curriculum required more explicit deliberation among programme developers and implementers towards a deeper and shared understanding of pedagogical assumptions and more congruent practice of transdisciplinary and transformative sustainability education. The reflective, theory-based approach enabled learning from evaluation and was captured in a shared refinement of the theory of change, which makes it explicit that learning from pedagogical innovations is not only for students but also for academics. The paper is an invitation to other innovators in sustainability science, education and evaluation in higher education, to share related findings.Significance: Through evaluative research, educators gained insight into how transformative sustainability education and transdisciplinarity play out in practice, and how theory-based evaluation can inform more transformative programme design. As higher education practitioners collaborating across continents and disciplines for systemic change, we noted that transformative concepts do not immediately translate into transformative practices, unless we critically and collectively reflect on practice and outcomes. Such (meta) reflection requires data and purposefully designed evaluation frameworks-in-use. This idea is not new, but its manifestation in practice was illuminative and could also be of scholarly interest to other curriculum and evaluation designers.
