📖 Reading Passage

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 load, allowing learners to focus their cognitive resources on the essential processing of information. However, intrinsic load, which is inherent to the complexity of the subject matter, cannot be reduced by instructional design alone. Researchers have found that overly complex diagrams or redundant text can increase extraneous load, thereby hindering learning outcomes. Conversely, well-structured materials that segment information into manageable chunks can enhance understanding by aligning with the natural limits of working memory. This theory has significant implications for curriculum design, particularly in STEM fields where abstract concepts often impose high intrinsic load.
