Resumen

Universities increasingly adopt SDG-anchored challenge-based learning (CBL) to develop innovation competencies, yet evaluations often rely on self-reports that cannot distinguish enthusiasm from demonstrated competence. This study evaluates the Innovation Challenge, an eight-week ecosystem-driven CBL (Ed-CBL) program integrated with Design Thinking (DT), and is reported using the TIDieR checklist to enhance replicability. We employed a convergent mixed-methods design: primary evidence comprised team-level performance across four mandatory deliverables and a summative pitch evaluated by an expert jury; secondary evidence assessed individual skill gains using the Youth Innovation Skills Measurement Tool (YISMT) in a non-equivalent groups pre-and post-test design. A milestone-based attrition analysis reveals a rigorous selection filter: only 55.5% (15/27) of verified teams over-came ecosystem constraints to complete the full cycle. Statistical analysis of skill gains (Welch’s t-test with Holm-Bonferroni correction) identified an initial differential gain solely in Creativity. However, a sensitivity analysis adjusting for significant baseline imbalances rendered this effect non-significant (p = .267); other dimensions also showed no significant changes. Consequently, we conclude that while Ed-CBL generates verifiable design outputs and technical performance, it does not yield robust short-term gains in self-reported innovation skills, highlighting the necessity of prioritizing performance evidence over self-efficacy in short-term programs.
