“…This issue has attracted many scholars to investigate the connection between self-regulated learning (SRL) and academic achievement situated in all educational levels; such as in primary education level (Dignath et al, 2008), in secondary education level (Bai & Wang, 2021;Guo et al, 2019;Harding et al, 2019), and even in higher education (henceforth HE) level (Peng, 2012). In the domain of English language pedagogy, several academic literatures highlighted the crucial role of learners' innate self-regulation in vocabulary learning, particularly for second or foreign language (L2/FL) acquisition (Bošnjak Terzić & Pavičić Takač, 2020;Nation, 2001;Schmitt, 2008Schmitt, , 2014Tseng et al, 2006) including in memorizing, remembering, and vocabulary acquisition. In fact, some previous literary works (Meara, 1980;Şahin Kızıl & Savran, 2018;Zheng, 2012) emphasized that learners without self-regulation capability tended to possess demotivation feelings (Kikuchi, 2009) and learning anxiety (Tseng & Schmitt, 2008) so that it can badly impact on depressing their academic achievement.…”
