This study examines the ways in which teacher collaboration supportsculturally responsive teaching within the South Korean educationalcontext. Employing an explanatory sequential mixedmethodsdesign, the research integrates quantitative and qualitativedata collected from South Korean school teachers. The findingshighlight collaboration as a key intra-organizational mechanism,enabling teachers to collectively navigate the complexities associatedwith culturally responsive teaching. Collaboration fostersa shared understanding of effective instructional practices andfacilitates adaptive teaching strategies by offering essential socialresources for navigating pedagogical uncertainty. The study arguesthat culturally responsive teaching should be understood notmerely as an individual endeavour aimed at addressing studentdifferences, but also as a collaborative effort that often seeks totranscend these differences in order to thoughtfully embrace classroomdiversity. Future research should further explore collaborativeapproaches to culturally responsive teaching in varied educationalcontexts internationally.
