“…This cognitive strategy has been extensively explored by experimental psychologists. Traditionally, this research has taken place in laboratory settings using diverse learning materials, such as word lists or pairs (Carpenter, 2009;Cranney et al, 2009;Halamish & Bjork, 2011;Peterson & Mulligan, 2013;Goossens et al, 2014;Abel & Bä uml, 2016), factual lists (Carpenter et al, 2008), face-name pairs (Carpenter & DeLosh, 2006), images (Pastötter et al, 2013), prose passages (Chan et al, 2006;Roediger & Karpicke, 2006b;Clark & Svinicki, 2014;Little & McDaniel, 2015;Bae et al, 2019), foreign language vocabulary (Kang & Pashler, 2014), brief multimedia lessons (Johnson & Mayer, 2009), PowerPoint presentations (Vojdanoska et al, 2009), and map-learning tasks (Carpenter & Pashler, 2007). However, no published studies have explored the testing effect on EFL students in particular.…”
