This chapter focuses on defining and illustrating multimedia learning of metacognitive strategies, and reviews the empirical literature on multimedia learning of metacognitive strategies. It provides suggestions for augmenting contemporary cognitive theories of multimedia learning, proposes empirically based principles for designing multimedia environments aimed at fostering metacognitive strategies, and recommends several areas for future research. The chapter specifies self-regulated learning (SRL) as a concept superordinate to metacognition that incorporates both metacognitive monitoring (i.e., knowledge of cognition or metacognitive knowledge) and metacognitive control, as well as processes related to manipulating contextual conditions and planning for future activities within a learning episode. More research on multimedia learning of metacognitive strategies is needed to determine the optimal length of various phases of training programs and their effectiveness in laboratory versus real-world settings, as well as the retention and transfer of strategies to other domains and computer-based learning environments (CBLEs).
