Wonder aims to explore how circus and experiential learning can be combined in practice. We believe this combination will lead to qualitative, meaningful, and innovative practices which will allow the introduction of new approaches in the work with vulnerable youth and which will contribute to the research for qualitative youth work in Flanders and Europe. Wonder wonders about the following three research questions: 1. How can we focus more on physical, non-verbal expression and communication within (experiential) learning? 2. How can we implement more wonderment and less frustration as a driver of (experiential) learning? 3. Which influence does physical contact have on models of group dynamics? The objectives are: 1* Applying innovative methods and improving of personal growth of youth workers. 2* Assess how methods are experienced by participants in a multicultural context. 3* Promoting the professional development of youth workers by obtaining insight into the theoretical and pedagogical framework of experiential learning. 4* Exploring new approaches to increase the impact of youth workers on the needs of vulnerable youth. 5* Developing an international network for the dissemination of the results within the European youth work.
