Educational practices for improvement of sustainability education at secondary school level

In the future of education, concepts of sustainability and recycling have to become integral parts of core subjects which require interdisciplinary collaboration beyond subject borders. Project-based Learning offers the perfect educational environment for such integration of knowledge not limited by single subject curricula or school curricula in general. At the same time, it offers a hands-on approach to actively in- volve students in the creation of products as well as the training of skills for critical thinking and problem-solving, but also increases their awareness regarding sustainability and environmental challenges. In this context, the goals of a circular economy are supported by such an educational approach combined with an environmental focus.
