The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational contexts, reducing extraneous cognitive load is crucial for effective learning. Extraneous load is generated by the way information is presented to learners, rather than by the inherent complexity of the material itself. For instance, a poorly designed diagram that requires excessive searching for labels can increase extraneous load, thereby hindering the acquisition of schema. Conversely, instructional designs that integrate visual and verbal information spatially and temporally can reduce this unnecessary burden, allowing learners to allocate more cognitive resources to the essential processing of the subject matter. This principle, derived from cognitive load theory, has significant implications for the creation of multimedia learning materials, suggesting that the manner of presentation is as important as the content itself.
