Europeans rank climate change among the most serious problems facing the world today (European Commission, 2021). Protecting the environment is important to 94% of EU citizens personally; 78% consider that environmental issues impact directly on their daily lives and health and almost all feel that urgent action is needed to tackle biodiversity loss (European Commission, 2020). Putting environmental sustainability at the heart of education and training means responding to the realities of the 21st century and equipping learners with the competencies they need to contribute positively to a sustainable society and economy. Teachers and trainers across Europe are already actively teaching for sustainability, often driven by their sense of responsibility to prepare future generations. At the same time, many educators say they lack training and support in sustainability education and training, in particular, regarding interdisciplinary approaches, active pedagogies, and the challenging subject matter. The MIRACLE project introduces deep and transformative changes needed to prepare learners for a rapidly changing society, economy, and future. The project responds to the need for a systemic green component of education and responds to the existing challenges as it: - adopts an interdisciplinary approach to learning about environmental sustainability, putting the learner at the center of the co-creation processes; - provides pupils with an interactive and immersive experience with Augmented Reality of the co-created digital comics, creating lasting knowledge and understanding of the topic and sparking their interest in science; - adopts the “Whole School Approach” where sustainability is embedded in all processes and operations; - provides schools with the basic science behind Climate Change, including data and tools on how to monitor the effectiveness of sustainability initiatives and efforts; - maps the national curricula for sustainability at all grades of primary education so that schools can easily integrate the project's learning activities; - offers teachers training and support in sustainability education and training, in particular regarding interdisciplinary approaches, active pedagogies, and the challenging subject matter. The proposal is based on multi-stakeholder participation, co-creation, social innovation and transformative learning as underlying concepts. There are 3 cross cutting areas in the proposal: curriculum and whole-school approach; use of comics literacy with Augmented Reality for sustainable development and regional cooperation supporting grassroots activity.
