The document summarizes a research project that analyzes university students' participation in co-designing learning scenarios. The project aims to study developing more authentic and learner-focused scenarios through a collaborative design process between students and teachers. The research uses a design-based methodology involving multiple iterative design cycles. Preliminary results found that configuration of co-design groups, task structure, and balancing structure with emergence are important factors. Ensuring participant comfort with roles and confronting student-teacher perspectives also impacted the critical issues in the co-design process.
