“…Oral production has been the most frequently investigated skill and, apart from vocabulary, the only domain for which there is an extensive body of research findings that, taken together, indicate that the SA context is more beneficial for oral proficiency gains than traditional AH instruction, even though not more beneficial than intensive AH instruction (Borràs & Llanes, 2021;Llanes, 2011). The constructs examined are varied and range from oral fluency (Freed, 1995;Freed et al, 2004;Hardison, 2014;Hardison & Okuno, 2022;Juan-Garau & Pérez-Vidal, 2007;Valls-Ferrer & Mora, 2014;Yager, 1998), oral accuracy (e.g., Hardison, 2014;Hardison & Okuno, 2022;Juan-Garau, 2014), pronunciation (Avello et al, 2012;Hardison, 2014;Hardison & Okuno, 2022;Llanes, 2011;Muñoz & Llanes, 2014) to global measures of oral proficiency (Brecht et al, 1995;Jochum, 2014;Magnan & Back, 2007;, with positive effects having been found for most measures, even though results are contradictory as far as pronunciation is concerned.…”
