Our project “Dangerously Curious” responds to a recurring and well-documented need among youth workers across Europe: the lack of knowledge, tools, and confidence to deliver STEM-related activities in non-formal education settings. In the past years, all partner organisations involved in this consortium have carried out projects with young people, teachers, and youth workers in both local and international contexts. Through project evaluations, needs assessment forms, and consultations with youth workers and educators, the same gap has repeatedly emerged: difficulties in making STEM attractive, engaging, and accessible to diverse groups of young people. This reality was reinforced by the participation of more than 400 youth and youth workers in partner activities since 2022, whose feedback consistently pointed to the same issue. The meta-analysis article “Non-formal education in STEM – potential and limits” (https://recreamaths.eu/blog/non-formaleducation- in-stem-potential-and-limits/), further confirms these findings. While STEM is essential for equipping young people with skills for the 21st century (Zailan et al., 2019), non-formal STEM methods remain underdeveloped and underfunded. Youth workers and teachers rarely receive training in inclusive, hands-on approaches such as robotics, coding with Arduino, or linking STEM to creativity and the arts. As a result, young people encounter STEM mostly through formal education, without the chance to experience its relevance to everyday life or its creative potential in community contexts. The issue is even more acute in rural and smaller communities, where access to innovative training is limited and resources are scarcer. Here, young people often perceive STEM as “boring” or “too difficult,” leading to reduced motivation to pursue STEM studies or careers. This contributes to persistent gender gaps, fewer opportunities for disadvantaged groups, and a growing mismatch between the skills young people acquire and the needs of the digital and green economy. Youth workers themselves highlight that they feel unprepared, lacking methodological knowledge and practical tools to integrate STEM into their daily youth work. Our partnership brings together six organisations from Romania, Czech Republic, Croatia, Bulgaria, Lithuania, and North Macedonia, each with strong experience in working with young people and youth workers. Although their profiles differ - NGOs focused on sustainability and inclusion, digital innovation hubs, organisations promoting intercultural dialogue, all confirm the same need: STEM is rarely integrated into non-formal youth work. Without proper training, youth workers cannot respond to the demand for equipping young people with digital, green, and problem-solving skills aligned with European Youth Goals and Erasmus+ priorities. This is the rationale behind our project: to upskill youth workers in innovative, non-formal STEM methods that make science and technology appealing, inclusive, and relevant for young people. By equipping them with these competences, the project ensures that communities, especially those with fewer opportunities, benefit from modern and engaging learning opportunities, bridging the gap between formal education and real-world applications. Aim: To strengthen the capacity of 24 youth workers from 6 European organisations to use innovative non-formal methods that make STEM education attractive, inclusive, and relevant for young people. Objectives: To develop the competences of 24 youth workers in planning and facilitating non-formal STEM activities during the training mobility. To improve the knowledge and practical skills of 24 youth workers in integrating digital tools, games, and hands-on experiments into STEM education. To enhance the ability of 24 youth workers to apply inclusive and gender-sensitive approaches in order to attract and engage a wider range of young people, including those with fewer opportunities, in STEM activities.
