“…Trenkic and Warmington (2019) found no evidence of language development in a six‐week EFL program; indeed, the authors called for urgent research that can inform pedagogical interventions in this population. Some research aimed at examining the effectiveness of longer programs (an academic year) has used postprogram academic performance to gauge language development in bridging programs (e.g., Faulkner, Ryan, Hurley, & Wang, 2017; Heitner, Hoekje, & Braciszewski, 2014; Oliver, Vanderford, & Grote, 2012; Thorpe, Snell, Davey‐Evans, & Talman, 2017; Van Viegen & Russell, 2019). In short, longitudinal studies that can “clarify the developmental trajectories of second‐language learners” (Melby‐Lervåg & Lervåg, 2014, p. 428) are urgently needed.…”
