["European Journal of Education, Volume 61, Issue 2, June 2026. ", "\nABSTRACT\nHigher education institutions are increasingly promoting cross‐disciplinary learning between the natural sciences and humanities. Several institutions have enacted policies that allow students to choose courses across disciplines to meet diversity objectives and graduation requirements. This study explores how these policies are implemented in classrooms, focusing on teachers' incorporation of inclusive curricula and pedagogy and on students' perceptions of these classes. Using qualitative methods and data from 53 participants, the study uncovers a policy paradox: a disconnect between policy goals and their real‐world classroom application. We found that university teachers often struggle to implement inclusive curricula and pedagogy in their cross‐disciplinary classrooms. Additionally, universities have not adequately prepared or trained these educators to address learners' diverse needs. As a result, few instructors respond promptly to students' backgrounds or needs during classes. Consequently, some students find the classes unengaging because the class content is challenging or they take courses merely to earn credits for graduation. We recommend that universities promote deliberate learning innovation in these diverse classrooms by providing faculty training to develop inclusive curricula and pedagogies aligned with policy objectives.\n"]
