The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, instructional designers often seek to manage cognitive load to optimize learning. According to cognitive load theory, learning is hampered when the working memory is overloaded with extraneous information that does not directly contribute to schema acquisition. For instance, a poorly designed diagram that requires excessive visual searching can impose unnecessary cognitive burden, thereby reducing the capacity for deeper processing of the core material. Conversely, well-structured materials that integrate related information can facilitate the construction of mental schemas, allowing learners to process complex ideas more efficiently. This theory has significant implications for the design of multimedia learning environments, where the goal is to reduce extraneous load while promoting germane load that is essential for understanding.
