This descriptive study presents the first research cycle with four synchronous telecollaborative language learning sessions on Zoom between Irish and Chinese teenagers. Intercultural Sensitivity Scale (ISS) post-questionnaire results show that the mean of interaction enjoyment scale is the highest compared to the other four categories, which implies that telecollaboration provides an enjoyable and authentic environment for Irish adolescent learners to experience communication with native speakers. However, low averages of ISS categories indicate some factors are at play such as short telecollaboration duration and potential technological issues. The gap between the previous needs analysis and current findings demonstrates that participants probably underestimated the challenge of engaging with Chinese native speakers, which would suggest that more scaffoldings and preparations are required for beginning-level learners before and during telecollaborations.
