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 designs align with human cognitive architecture. Intrinsic load is the inherent difficulty of the material itself, while extraneous load is generated by the way information is presented. Germane load, on the other hand, is the effort devoted to processing and understanding the material, which directly contributes to learning. Research indicates that poorly designed materials can unnecessarily increase extraneous load, thereby reducing the cognitive resources available for germane processing. Therefore, educators should minimize extraneous load by simplifying presentations, while managing intrinsic load through sequencing complex tasks. This approach optimizes the working memory capacity, facilitating deeper learning.
