To prepare students for addressing wicked problems such as climate change and inequality, higher education must foster systemic and interdisciplinary thinking. We developed a flexible, interactive workshop grounded in sustainability goals and transitions theory to promote abductive reasoning across disciplines. Using cases on food waste, fashion, and e-waste, the workshop was tested in four diverse settings in 2025. Findings show that while tool format (manual vs. digital) had a limited impact, structured facilitation and clearly framed tasks were essential for engagement. We offer insights for educators seeking adaptable, experiential methods to embed sustainability in diverse learning environments.
