"The EU Climate Action Strategy considers young and childhood students a critical sector of civil society to promote Climate Action (CA). Youth and childhood ’s commitments (or lack of it) today will lead to institutional commitments (or lack of them) tomorrow. However, the Eurobarometer surveys highlight a noticeable gap between the concern of children and young Europeans for Climate Change (CC) and their personal commitments & skills on CA.Research conducted by education sciences experts confirm that scientific knowledge is not enough to change children and young attitudes to actively engage with CC. They require a social conscience and a citizen responsibility that emerge from values and education.In pre-school/primary formal education, the pupils are motivated about topics related to earth care and CC. But in the school´s curriculum these topics are only “touched on” and mainly in subjects related to science. Thus, motivation, opportunity and ability to act decrease when the pupils become aware that CC and CA seem not linked to their cultural, emotional and ethical values. Recommendations for new methods in young and childhood formal education are central to the EU Climate Action Strategy. With that on the mind, it is necessary that future teachers of pre-school & primary learn about how they can link the scientific knowledge about CC with cultural, emotional and ethical values to more effectively educate children’s minds and acts.The religious beliefs are some of the most powerful values to significantly influence a community’s understanding and experience of CC adaptation. Over the past years, most religious communities have released statements on CC and the need to educate in Climate Action. One of the most active religions is the Catholic one. The Francesc Pope´s encyclical LS 201 related to education on the UN Sustainable Development Goals has had a lot of impact on an international level in the context of the Agenda 2030.The CHANCES consortium is composed of 3 universities and a EdTech SME. These 4 organizations, expert in education sciences, catholic religion and sustainable development declare the ambition to innovate through a powerful tool: to construct a 3 ECTS itinerary for education degrees/masters coupled with new assessment mechanisms by means of digital OERs. With this itinerary, future teachers of pre-school & primary schools will learn how to bring the CC subject into the classroom linking Catholic religion values and science. These 4 organizations will work in association with several local working groups consisting of pre-school/primary schools and Catholic bodies which are responsible for the curriculum of the subject of Catholic religious education. The CHANCES methodology combines, for the first time, scientific knowledge with some of the most powerful values & beliefs, the religious ones, increasing the effectiveness of the formal education system’s understanding and experience of CC competences. The project aims to invest in HIE professors and students of education sciences degrees and postgraduate studies. Thanks to CHANCES, they will start and lead their CA venture for when the moment will come to teach in pre-school & primary schools.CHANCES develops next IOS:• An innovative METHODOLOGY will permit that the future teachers of pre-school/primary, who want to be specialised in the subject of catholic religious education, will learn how to bring the CC subject into the classroom linking religion and science.• By means of the new methodology, a new CURRICULUM on the topic ""How Catholic religion education can educate pupils on CC and CA"" will be developed for degrees/master´s in sciences education and Catholic religious education. The course will consist of 3 ECTS consisting of few face-to-face classrooms, most instruction being e-workshop and self-directed learning via e-portfolio.• A European E-PORTFOLIO will be adapted and improved. It will be used by students of the new CC curriculum to collect artifacts & reflections. The eportfolio will serve to:- Evidence of the new kind of competences & skills needed to link religion and science for CC teaching- Use it by HIE students during their practices at the schools. The result will be the first digital repository of best practices related to learning CA through religious education- Make HIE students more digitally literate when teaching religion related to CCThe IOs will be piloted in a degree and/or master at 3 universities and at pre-school/primary schools in Spain, Italy & Poland. Training & face to face or blending learning implementation actions, one transnational and several local ones, will ensure that the project is not only FOR professors, students & alumni but also BY them. CHANCES´ impact on deans, schools ‘principals & policymakers will make them permeable to the acquisition and validation of CC skills linked with the cultural and ethical values of students to increase their commitment towards CA."
