“…However, there is little evidence for both assumptions. First of all, research has shown that students do not apply and acquire self-regulation skills merely by engaging in self-regulated learning, but rather need additional training or instructional support such as prompts or tutoring (e.g., Aleven & Koedinger, 2002;Azevedo & Cromley, 2004; Van den Boom, Paas, & Van Merriënboer, 2007;Van den Boom, Paas, Van Merriënboer, & Van Gog, 2004). Secondly, although the assumption seems to be correct that personalized instruction can foster learning more compared to non-personalized instruction (e.g., Anderson, Corbett, Koedinger, & Pelletier, 1995;Camp, Paas, Rikers, & Van Merriënboer, 2001;Koedinger, Anderson, Hadley, & Mark, 1997;Salden, Paas, Broers, & Van Merriënboer, 2004), it is questionable whether self-regulated learning actually results in the adaptivity to students' needs that is required for effective personalized instruction.…”
