The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, instructional design aims to manage this load to optimize learning. According to cognitive load theory, learning is hampered when the working memory is overloaded, as it has a limited capacity. However, recent research suggests that the theory's application is not one-size-fits-all. For instance, while reducing extraneous load (irrelevant information) generally benefits novices, it may hinder experts who benefit from more complex tasks that challenge their existing schemas. This nuance highlights the importance of tailoring instructional methods to the learner's level of expertise, rather than applying a universal reductionist approach.
