ESD is associated with high standards. For example, the UN postulated as its vision for the World Decade (2004–2015) that ESD should ‘open up educational opportunities for all people [...] that enable them to acquire knowledge and values and learn behaviours and lifestyles that are necessary for a future worth living [...]’ (DUK 2011, 7). Accordingly, the materials in the ESD BOX aim to empower children and young people to shape their own development – and, by extension, social and global development – in a sustainable manner. This should give them the opportunity to acquire the values, knowledge and skills necessary for shaping their own lives and society in a sustainable manner (cf. ibid.).
The ESD BOX therefore promotes sustainability knowledge that is integratively conceived from the subject didactics about the global ecological, socio-cultural and economic interrelationships and the various problems that require action in the sense of sustainable development. This knowledge is linked to an understanding of the interdependent relationships between global, regional and local structures and processes (cf. Hoiß 2019, 34).
The materials in the ESD BOX primarily focus on the acquisition of so-called design skills. The term “design skills” was coined in the 2000s by educational scientist Gerhard de Haan to systematise the facets of a comprehensively conceived ESD for teachers and learners on the one hand, and to make them operational on the other. The aim is therefore to help gain an overview of the requirements of ESD and, at the same time, to enable its intentional and well-thought-out implementation in a wide variety of learning environments.
Specifically, acquiring design skills has two aspects: First, it is about knowing how children and young people, but also adults, can promote sustainable development processes and how they can recognise processes that are not sustainable or less sustainable. Secondly, people are guided and encouraged to acquire and reflect on values and skills that motivate them to act sustainably and enable them to become active and effective in promoting sustainable development, both independently and with others (cf. DUK 2011). At the same time, the teaching units and methodological patterns of the BNE-BOX integrate, to varying degrees, the 17 global sustainability goals (SDGs) formulated by the United Nations in its Agenda 2030.
Based on the ESD design competencies in Gerhard de Haan's categorisation (2008), competencies for learners in the areas of subject-specific, social and personal skills were first formulated for implementation in the materials. The aim is not for each teaching unit to cover all these aspects. Rather, they serve as a guide for teaching activities with a special focus on ESD: the learner competencies were expanded in the ESD BOX to include teacher competencies that enable discursive and value-reflective ESD teaching. The following graphics provide an overview of the ESD competencies for learners and teachers.
