This article argues that participative approaches, such as those found in enterprise or entrepreneurship education, allow several factors to influence learning activity. The "Mini-enterprise" (Young Enterprise) approach is one where students set up and run their own business during a school year. This article is based on the analysis of interactional processes in four mini-enterprises in post-16 education. Given the emphasis on progressive ideas in entrepreneurship education in general, it is important to understand how students themselves form the learning activity. The analysis shows how ideas about friendship, school and business all contribute to students' interaction and to forming the learning process. In order to explore how students' agency is informed by different sets of ideas, the article applies Joas' theory of creative action. This allows a discussion of how students' personal and professional interests interact in productive and less productive ways in the learning activity.
