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 Sweller's cognitive load theory, learning is hindered when the intrinsic load (complexity of the material) and extraneous load (manner of presentation) exceed the learner's capacity. However, recent research suggests that a moderate level of germane load, which involves the deliberate construction of schemas, can enhance long-term retention. For instance, a study by Kalyuga (2011) found that novice learners benefit from worked examples, while experts may experience a 'reversal effect' where such examples impede performance due to redundant information. This implies that instructional methods must be adapted to the learner's level of expertise, rather than being universally applied.
