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, allowing learners to focus on intrinsic load and germane load. Intrinsic load is the inherent difficulty of the material itself, which cannot be altered without changing the complexity of the subject. Extraneous load is generated by the way information is presented, such as unnecessary graphics or confusing instructions. Germane load involves the mental resources devoted to processing and integrating new information into long-term memory. Research indicates that overly complex presentations can overwhelm students, hindering their ability to learn. Therefore, educators are advised to simplify visual aids and provide clear, structured explanations to optimize working memory capacity.
