“…Previous studies about engagement in MOOCs focused on the engagement patterns (Ferguson & Clow, 2015;Khalil & Ebner, 2017;Phan, McNeil, & Robin, 2016) and the impact of engagement on performance or completion (de Barba, Kennedy, & Ainley, 2016;Freitas et al, 2015;Goldberg et al, 2015;Onah et al, 2014). Scholars have mentioned that student engagement contains multiple components, but most studies consider the "engagement" as a multidimensional uniform variable, or focus on one dimension of engagement (such as behavioral engagement) (Appleton, Christenson, Kim, & Reschly, 2006;Cho & Cho, 2014;Fredricks, 2011;Li, Zhang, Bonk, & Guo, 2015;Liu, Calvo, Pardo, & Martin, 2015;Reeve, Jang, Carrell, Jeon, & Barch, 2004). However, a small amount of literature indicates that there is a certain interrelationship between different dimensions of engagement (Cheung, Shen, Lee, & Chan, 2015;Fang, Zhao, Wen, & Wang, 2017).…”
