“…Within all the different elements that go into English for Specific Purposes (ESP), the importance of grammar has been re-acknowledged and confirmed (Belcher, 2006;Ibrahim, 2010;Johnson & Lyddon, 2016), as have the positive pedagogical implications of Computer-Assisted Language Learning (CALL) in ESP (Belcher, Johns & Paltridge, 2011;Paltridge & Starfield, 2013;Walker et al, 2014;Felices Lago, 2016;Bonsignori, 2018). The problem of motivation has also been a frequent topic in recent research regarding ESP both in conventional and in CALL classrooms (Brown, 2007;vaičiūnienė & užpalienė, 2010;İlin, Kutlu & Kutluay, 2013;González Ardeo, 2016;Schug & Le Cor, 2017). However, the specific impact of CALL on motivation and grammar learning lacks demonstration, testing and measuring during a real learning process in the context of ESP.…”
