This quantitative study investigates students’ perceptions of a virtual language exchange implemented between two higher education institutions. By examining two successive cohorts, the research aimed to identify shared patterns, institutional differences, and changes over the duration of the exchange.

Data were collected through two opinion questionnaires administered at the beginning and at the end of the exchange in each academic period. Quantitative analyses included descriptive statistics, independent-samples t-tests, chi-square tests, and Pearson correlation analyses. The results were examined globally, by institution, and longitudinally to capture overall trends and contextual variation.

Across both successive cohorts, students entered the exchange with strong initial motivation, particularly a desire for intercultural openness, alongside comparatively low self-confidence in the target language. By the end of the exchange, participants reported high satisfaction with their exchange partners, positive evaluations of the interactional framework, and increased self-confidence, involvement, and cross-cultural awareness. Institutional differences emerged in specific areas, such as perceived language level, satisfaction, and cultural learning, but these did not substantially alter the overall pattern of findings. Correlation analyses revealed strong and significant relationships among key variables, indicating that linguistic development, learner engagement, self-confidence, and intercultural knowledge were closely interconnected and mutually reinforcing.

The findings suggest that virtual language exchanges supported by clear guidelines and a structured pedagogical design can enhance undergraduate learners’ language skills and cultural growth. The study contributes to existing research by demonstrating the consistency of these outcomes across cohorts and institutional contexts, and by highlighting the dynamic links between affective, linguistic, and cultural dimensions. These results support the integration of virtual language exchanges as a sustainable and effective component of internationalization at home in higher education since they offer students opportunities for authentic interaction and sensitivity to cultural diversity without physical mobility. Therefore, they can promote multilingualism and intercultural understanding, the keystone of democratic societies.
