“…The results of this study, along with several other studies (e.g., Tian & Macaro, 2012), suggest that intentional FFI is superior to incidental vocabulary exposure in classroom contexts. However, note that a number of studies have shown that a limited amount of vocabulary can also be learned incidentally (e.g., Bisson, van Heuven, Conklin, & Tunney, 2014;Gablasova, 2014;Liu & Todd, 2016;Newton, 2013;Pellicer-Sánchez, 2016).…”
