The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational psychology, cognitive load theory suggests that learning is most effective when instructional materials are designed to minimize extraneous cognitive load, thereby freeing resources for the intrinsic processing essential to understanding complex subjects. Intrinsic load is determined by the difficulty of the material itself, whereas extraneous load is influenced by how the information is presented. For instance, a poorly designed diagram may force learners to split their attention between disparate sources of information, increasing extraneous load and hindering comprehension. Conversely, integrating related text and visuals can reduce this unnecessary burden. Research indicates that overly complex tasks, if not scaffolded appropriately, can overwhelm learners, leading to decreased performance. Thus, educators must carefully structure content to manage cognitive demands, particularly in STEM fields where abstract concepts are prevalent.
