There is a growing body of research evidence showing the need to identify and integrate innovative yet effective pedagogical approaches in climate change education. Among the ones proposed as most appropriate are those that seek to ground scientific knowledge about climate change in students’ personal real-life situations, as well as those that engage them in active and experiential learning experiences. Based on this rationale, we propose an interdisciplinary approach to teaching and learning about climate change that draws on the combination of two different disciplines and their research methodologies: citizen science and environmental oral history. We first justify from a theoretical point of view the synergy between the two approaches in the context of climate change education, and then present an educational case study in which we applied and evaluated it. Fifteen Greek high school students participated in an educational fieldtrip to explore the relation between forest fires and climate change in the Parnitha National Park, a protected nature reserve at the top of the highest mountain in Attica. The students first engaged in citizen science processes recording and identifying plant species with the use of the Pl@ntNet app and then conducted and analyzed a life narrative interview with a civil protection volunteer and forest fire expert to gain a more comprehensive understanding of the interplay between the two issues. We discuss the added pedagogical and learning value of this approach to promote interdisciplinary understanding of the complex manifestations of climate change in local contexts.
