“…In general, the retention theory basically discusses the factors that influence student retention positively or negatively (Kinder et al, 2002). Several theoretical models of retention have been offered in both domains of traditional learning and DL (Bean & Metzner, 1985;Boshier, 1973;Boyles, 2000;Braxton et al, 1997;Frankola, 2001;Garland, 1993;Kember, 1981;Khan et al, 2018;Kinder et al, 2002;McEwen & Gueldenzoph, 2003;Morris & Finnegan, 2005;Puspitasri & Oetoyo, 2018;Tinto, 1975Tinto, , 1982Tinto, , 1993Sweet, 1986;Tillman, 2002;Traxler, 2018 Cabrera, Castaneda, Nora, and Hengstler (1992) pointed out that individual attrition from academic institutions can be ascribed to a longitudinal process of interactions between an individual and other members of the academic and social systems of the institution, herewith stressing the importance of individual factors and institutional involvement in attrition and retention research. Bean and Metzner (1985), on the other hand, considered attrition behaviour as a function of the person and his/her environment, and, given the fact that DL students do not regularly attend classes on campus, emphasized the need to take external environment factors into account, rather than so-called social integration variables that mainly affect traditional students on campus (Boyles, 2000).…”
