“…Much research on the linguistic benefits of SA has examined the development of L2 oral production abilities. This research has found positive effects of SA for overall proficiency (e.g., Di Silvio, Diao, & Donovan, 2016; Segalowitz & Freed, 2004), fluency (e.g., Kim et al., 2015), pronunciation (e.g., Díaz–Campos, 2004; Lord, 2006), and lexical complexity and richness (e.g., Kim et al., 2015; Serrano, Tragant, & Llanes, 2012). Another facet of L2 oral production abilities that has been examined, but has yielded less uniform results, is grammatical accuracy, with some studies showing improvement (e.g., Isabelli & Nishida, 2005; Serrano et al., 2012) and others finding no significant effects (e.g., Collentine, 2004; DeKeyser, 2010).…”
