While learning in Internet-based environments, students rely on metacognitive knowledge to organize, record, monitor, and review their learning path. In this experience, they may reveal either a “surface” or “deep” approach. In this study, 509 university students were administered the adapted versions of the ‘Metacognitive Knowledge regarding Internet-based Learning’ questionnaire and of the ‘Approaches to Internet-based Learning’ questionnaire. Positive correlations between metacognitive knowledge and approaches to Internet-based learning environments emerged: The metacognitive attitude was associated to a concerned and critical approach to learning whereas the negative attitude about Internet-based learning was associated to the surface approach. Students showed a global understanding of the peculiarities and opportunities of Internet-based learning environments rather than empathize a single cognitive or metacognitive feature.
