Cultivating Curiosity and Metacognition Through SDG-Focused Problem-Based Learning in a Global Classroom

Communication and writing skills are critical for employability and leadership in sustainability and STEM fields, but few studies examine how interdisciplinary, problem-based learning (PBL) environments foster these competencies amongst undergraduates. This three-year study examined how human resource management (HRM) and Chemistry students collaborated on Sustainable Development Goal (SDG)-themed projects within a Global Classroom model. We used LIWC-22, a validated text analysis tool to assess students’ written reflections about their discipline-specific PBL exercises (e.g., debates about UBI) and their SDG-focused inter-disciplinary group projects (e.g., vaccine access). We found that the HRM students ( n = 84) demonstrated increased use of curiosity and cognition language during in-person and synchronous collaboration contexts. Chemistry students collaborating synchronously with their HRM teammates exhibited enhanced curiosity in their writing, though findings for this group are tentative due to the small sample size. Our findings suggest that both discipline-specific and SDG-focused interdisciplinary PBL activities can improve undergraduates’ metacognitive skills and their curiosity, which are critical for addressing sustainability challenges. Our Global Classroom offers a scalable model of how SDG-focused PBL activities can be used to create collaborations between STEM and management undergraduates and enable them to develop context-specific solutions for global sustainability challenges while improving their communication and writing.
