“…For example, Martinsen () investigated a 6‐week program in Argentina and reported no direct correlation between the amount of time participants spent with native speakers and improved oral skills, attributing the results to the repetitive nature of the interactions in which many L2 learners engaged. Instead, previous studies have found that it is substantive nature of interactions (e.g., those that go beyond repetitive daily conversations and simple transactional language), rather than the frequency of interactions, that has been shown to predict gains in L2 skills (Arnett, ; DeKeyser, ; Freed, ; Isabelli‐García, ; Kinginger, ; Lafford & Collentine, ; Llanes Baró & Serrano, ; Martinsen, ; Morales‐Front & Sanz, ; Serrano et al, 2016). Specifically, several studies have shown that study abroad experiences may not explicitly facilitate the kinds of interaction that support progress toward higher levels of proficiency (DeKeyser, , ; Grey, Cox, Serafini, & Sanz, ; Magnan & Back, ; Marijuan & Sanz, ).…”
