“…The third model, labeled the mixed model, assumes that intelligence and metacognition are somehow correlated, but they maintain their own unique contribution to the prediction of learning performance (Veenman, Elshout, & Meijer, 1997;Veenman, Kok, & Blöt, 2005). Veenman and Verheij (2003), , and Van der Stel and Veenman (2008) recognize that there is evidence in favor of these three models, but their studies have shown that metacognitive skills are as important as, or more general than intelligence to explain academic achievement and learning outcomes, and that intelligence and metacognition are correlated, which would support the third model.…”
