The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, instructional designers often aim to manage cognitive load to optimize learning. According to cognitive load theory, learning is hampered when the working memory is overloaded with extraneous information that does not contribute to schema construction. However, intrinsic load, which is the inherent difficulty of the material, cannot be reduced without simplifying the content. A well-designed instructional material should minimize extraneous load while preserving the necessary complexity of the subject matter. Recent studies suggest that the use of multimedia can either enhance or hinder learning, depending on how the visual and auditory channels are integrated, thereby influencing the overall cognitive load experienced by learners.
