The Thematic Line of Quality Education aligns with the objectives outlined in SDG 4, which aims to guarantee inclusive and high-quality education for all while fostering lifelong learning opportunities. In response to the challenges facing education in the 21st century, this line aims to contribute to the development of research and intervention in the various fields of Education, Training, and Development, promoting collaboration with communities, namely the promotion of quality of life, social transformation, culture, citizenship, and sustainable development. It emphasizes critical thinking, challenging stereotypes, and equipping individuals with the skills and confidence to support change toward a fairer and more sustainable world. This thematic line will also incorporate research into curriculum-related issues and different didactics, within the scope of in-service and pre-service teacher education.
