Whether we view sustainable development as our greatest challenge or a subversive litany, every phase of education is now being urged to declare its support for education for sustainable development (ESD). In this paper, we explore the ideas behind ESD and, building on work by Foster and by Scott and Gough, we argue that it is necessary now to think of two complementary approaches: ESD 1 and ESD 2. We see ESD 1 as the promotion of informed, skilled behaviours and ways of thinking, useful in the short-term where the need is clearly identified and agreed, and ESD 2 as building capacity to think critically about what experts say and to test ideas, exploring the dilemmas and contradictions inherent in sustainable living. We note the prevalence of ESD 1 approaches, especially from policy makers; this is a concern because people rarely change their behaviour in response to a rational call to do so, and more importantly, too much successful ESD 1 in isolation would reduce our capacity to manage change ourselves and therefore make us less sustainable. We argue that ESD 2 is a necessary complement to ESD 1, making it meaningful in a learning sense. In this way we avoid an either-or debate in favour of a yes-and approach that constantly challenges us to understand what we are communicating, how we are going about it and, crucially, why we are doing it in the first place.

Over recent decades, education policy has been preoccupied with economic growth while paying insufficient heed to global sustainability challenges. International initiatives to promote education for sustainable development (ESD) have been hampered by a lack of clarity on how to implement this form of education. To address this concern, a Rounder Sense of Purpose (RSP) began as a three-year EU-funded project that set out to develop a practical accreditation model for educators working on ESD. Expert and user opinion was sought through several rounds of structured consultation with over 500 people, chiefly using a Delphi approach, to develop and validate the model. The resulting framework comprises 12 competences, each with three learning outcomes and several underpinning components. This is supported by a range of activities largely reflecting a constructivist pedagogy. A range of assessment techniques have also been piloted within the project although this remains an area for further enquiry. Ultimately, it was decided not to design a single qualification template because defining the award to such a level of detail would make it more difficult to apply across multiple jurisdictions. Partners also felt that such an approach would atomize learning in a way that runs counter to the holistic principles of sustainability. RSP provided a rich learning experience for those involved and has already demonstrated its potential to extend its impact well beyond the original participants.

Secondary school students are granted few opportunities to change their world, yet they are expected to engage fully as citizens the moment they leave school. This issue is growing starker with multiple global crises contributing to mental health concerns. This situation stimulated a practical education for sustainability project designed to promote student agency by supporting small, student-led, community-based projects, planned and supported within the secondary school context. This research ran alongside the project in order to investigate (a) the impact of implementing these projects on the students involved and (b) the implications of this for their teachers. The research approach was based on Cultural-historical Activity Theory, which explores the learning generated through multi-layered interactions within a given activity system. In stimulating student agency, it was clear that the project had challenged existing practice. Students sensed a shift in power relations, remarking on how teachers respected and listened to their opinions. Those teachers who appeared more authoritarian appeared to experience the greatest transformation although ceding power did not come naturally, particularly where this challenged notions around teacher responsibility. In this way, teachers’ professionalism threatened to become the means by which they withheld power from their students. Implications of this for schools and policy are considered.

As schools seek to implement frameworks of education for sustainable development it is inevitable that they will encounter contradictions between their own aspirations and external demands. To analyse these contradictions through the lens of teachers-in-context, this research uses Cultural-historical Activity Theory that views schools as activity systems and reveals contradictions within those systems. Interviews with teachers and headteachers from a sample of twelve schools (primary, middle and secondary level) in England highlight contradictions that occur at different strategic levels in the school. A perspective document, comprising contradictory statements gathered from interview transcripts, reveals the extent to which these contradictions are shared among interviewees. A striking feature of the data is that teachers do not recognise these contradictions themselves. Analysis of the data reveals how teachers respond to contradictory situations. Responses include a sense of powerlessness, varying degrees of accommodation and a reframing of contradictions through ‘expansive learning’. This paper proposes a process for identifying and assessing contradictions in schools and suggests that, by making their responses to contradictions explicit, teachers can present learners with authentic examples of contextualised learning.
