The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational psychology, it is theorized that instructional design can significantly influence this load. When information is presented in a complex or disorganized manner, learners may experience an extraneous cognitive load, which impedes the process of schema construction. Conversely, well-structured materials that align with the learner's prior knowledge can facilitate intrinsic load management, allowing for more efficient learning. Recent studies suggest that multimedia presentations, while engaging, may inadvertently increase extraneous load if they include redundant or irrelevant stimuli. Therefore, educators are advised to minimize such distractions to optimize the transfer of information into long-term memory. This theory underscores the importance of deliberate pedagogical planning in enhancing educational outcomes.
