Research on the effectiveness of short-term study-abroad (SA) programs for improving oral skills has shown mixed results. In this study, 24 L2 German learners (L1 English) provided pre- and post-SA speech samples addressing a hypothetical situation and completed surveys on cross-cultural interest and adaptability; L2 communication affect, strategies, perceived competence; and L2 contact. Native speakers (NSs) provided ratings for pronunciation, fluency, grammar, vocabulary, and accentedness. Results revealed significant improvement in all oral skills and positive changes in the socio-affective factors. Participants who reported more positive affect in interactions with NSs pre-SA tended to spend more hours in extended interactions with them while abroad. These hours were related to increased positive communication affect post-SA. No significant relationships were found between L2 contact and gains in oral skills. Homestay experiences were positive, providing opportunities for extended interactions and cultural knowledge. For classroom learners, findings suggest a role for e-languaging tasks with NSs.
