3D Education: Democracy, Diversity, and Dialogue" was an Erasmus+ KA1 long-term training course targeting youth workers and educators interested in global citizenship education. The project had clear objectives, including developing awareness and attitudes among youth in Luxembourg and Partner/Programme countries regarding the complexities of "being a citizen." It aimed to support the professional development of youth workers and leaders, empowering them to integrate citizenship into their work and implement projects that exemplify the connection between European Citizenship, Human Rights/HRE, Democracy, and Intercultural learning alongside foundational values. The project, which consists of two residential training courses and a local "homework" phase, was open to educators from both formal and non-formal education systems, such as trainers, teachers, social workers, youth workers, and staff from NGOs and other entities. The successful hosting of the first residential TC in Luxembourg and subsequent follow-up activities demonstrated tangible progress. Objectives achieved during the initial residential courses and the next homework phase included the development of awareness and attitudes among youth, highlighted through theoretical interactive sessions and a visit to the European Museum of Schengen. Participants gained insights into citizenship as a matter of rights and dignity, emphasizing compromises. Both Luxembourgish and foreign participants understood the importance of patience in achieving long-term goals related to citizenship. Furthermore, the project successfully empowered youth workers, organizations, and educators to implement projects demonstrating the connection between European Citizenship, Human Rights/HRE, Democracy, and Intercultural learning. During the "homework" phase, some participants implemented local workshops focusing on non-formal education, European citizenship, and diversity. Notably, participants from Portugal and Italy conducted sessions on networking, cooperation, and project development, while Armenian participants shared innovative tools with their sending NGO staff for non-formal educational activities. This successful collaboration aligned with the broader objectives of the project, fostering awareness, empowerment, and the practical implementation of citizenship values across diverse contexts. The project, now concluded, has left a positive impact on the participants and communities involved.
