A mixed methods study of student leadership development across US and South African cultures through innovative exchange

Purpose This paper aims to examine how Collaborative Online International Learning (COIL) enhances leadership and employability skills among US and South African students. Drawing on human capital and transformational leadership theories, it explores COIL as a pedagogical model that develops teamwork, communication and cultural fluency, bridging academic learning with career readiness. Design/methodology/approach This mixed-methods study of 138 US and South African undergraduates used pre- and post-surveys and Cole’s content analysis to assess COIL’s impact on career readiness skills and intercultural competencies. Findings Results revealed significant gains in teamwork, communication, leadership and intercultural skills. South African students demonstrated gains in teamwork and leadership, US students in communication, ethics and intercultural understanding. Qualitative data highlighted empathy and adaptability, confirming COIL’s ability to advance global awareness and collaboration. Research limitations/implications Limitations include a small, non-random sample and reliance on self-reported data, restricting generalizability. Future research should examine longitudinal effects, multi-institutional cohorts and disciplinary variations to better understand COIL’s impact. Practical implications Integrating COIL into curricula can enhance competencies valued by employers and support internationalization without significant cost or logistical barriers. Social implications The study provides evidence of COIL’s measurable impact across two cultural contexts, informing educators, policymakers and employers about the potential of virtual collaboration for leadership development. Originality/value This study provides a first-hand account of innovative pedagogy involving international student collaboration between Durban University of Technology, South Africa and Queens College, the City University of New York, USA.
