📖 Reading Passage

The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational contexts, cognitive load theory suggests that instructional design should minimize extraneous cognitive load to facilitate learning. Extraneous load is generated by the manner in which information is presented to learners, such as unnecessary graphics or redundant text. In contrast, intrinsic load is inherent to the complexity of the material itself, and germane load is devoted to processing and constructing schemas. Research indicates that when extraneous load is high, learners have fewer cognitive resources available for deep understanding, leading to poorer performance on complex tasks. Therefore, effective instructional materials should streamline presentations to reduce irrelevant demands on working memory, allowing learners to focus on essential information.
