“…Under some circumstances this may be problematic, as existing knowledge is an important predictor of future learning (e.g., Schneider & Bullock, 2009). Thus, to constructively engage with learning materials, learners need basic knowledge on all to-be-learned core concepts, on which they can build, for example, by constructing principle-based self-explanations (Renkl, 2014), by devising well supported arguments (Noroozi, Weinberger, Biemans, Mulder, & Chizari, 2012), or by working out a comprehensive problem solution (Rummel & Spada, 2005). Such constructive, individual engagement is also the basis for effective interactive knowledge construction (Chi & Wylie, 2014).…”
