Our project proposal is called “What a wonderful world!” and it’s main objective is to raise awareness about climate change and environmental issues in our schools and local communities. In order to achieve this, students should develop the knowledge, skills, and competencies needed on the basis of scientific methods, disciplines, and evidence, and contribute to the mitigation of and adaptation to climate change. Another core objective of our project has to do with the understanding of sustainability and adopting a new mindset about our economy, energy, living style, and behavior. Also crucial to our project is cooperation and understanding that we are all part of the solution. We are aiming to produce and evaluate innovative teaching approaches to integrate quality climate change education for sustainable development in school education through interdisciplinary practices, STEM and whole-school approach.
