Thematic network of the data corpus
Challenges	Emerging Themes
Lack of adequate teacher training Lack of teacher/researchers Unclear link between EfS curriculum and Education theories Not-applicable in my University module Student - centred learning not promoted in regular classes	Action-oriented learning (active learning) Cooperative learning, team work, peer feedback Problem-based learning Students taking ownership Level-Appropriate Activities Ed for sustainable development IBSE (guided or open inquiry) Experiential learning Student agency Inclusive education Innovative pedagogies Student-centred learning Inter-disciplinarily Projects - Experiments
Recommendation	Teacher Training for Innovation pedagogies and action research linked to EfS
Lack of transparency Lack of motivation: Students, Teachers, Colleagues, Principals, Authorities	Activation of student experience - personalisation Awareness-raising activities Transparency and motives for all stakeholders Student engagement/Cooperation and team work Critical thinking (being open-minded, dealing with bias, stereotypes) New technologies Acting local & Thinking global
Recommendation	Teacher training in motivation strategies and inclusivity via digital technologies
Lack of time due to School curriculum limitations Unrealistic bulk of deliverables Teacher exhaustion /work load Organisation issues School principals not facilitating EfS programmes due to lack of finances or promotional prospects Lack of recognition - Authorities - promotional purposes/ personal fame Lack of vision - School principals not facilitating EfS programmes due to lack of finances or promotional prospects	EfS goals should be linked with teacher evaluation EfS goals should be linked with promotion prospects in education EfS goals should be linked to school performance/ranking EfS goals should be linked to University ranking
Recommendation	Coding and establishing sustainability goals within a hierarchical system across schools and universities
Segregation: Discipline-specific deliverables Cognitive dissonance Lack of inclusivity Modularised curriculum Disparate outreach: Lack of sustainable networks	Modules vs Inter-disciplinarily EfS should be incorporated in each module EfS should be included in all Science-related modules Students and teachers should be more tolerable to subjective norm School visits strict protocol = delays or prohibition of school visitors
Recommendation	Incorporate EfS in all modules all levels Integrate disparate implementations into a coherent EfS data system
