“…Nearly four decades after first proposing his hypothesis, Cummins concluded that ''The common underlying proficiency makes possible transfer of concepts, skills, and learning strategies across languages'' (Cummins, 2016, p. 940). However, most studies which investigated the LIH in relation to L1 and L2 literacy, focused on reading rather than on writing (see Dressler & Kamil, 2006, cited in Cummins, 2016; see also Chuang et al, 2012;Van Gelderen, Schoonen, Stoel, De Glopper, & Hulstijn, 2007), although the link between reading and writing (e.g. Fitzgerald & Shanahan, 2000) and the possibility of transfer between languages for writing have been studied to some extent as well.…”
