📖 Reading Passage

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 aim to manage cognitive load to optimize learning. According to cognitive load theory, there are three types: intrinsic, extraneous, and germane. Intrinsic load is inherent to the complexity of the material itself, while extraneous load is generated by the way information is presented, which can be reduced through better instructional design. Germane load, on the other hand, is the mental resource devoted to processing and understanding the material, which is beneficial for learning. Research suggests that when extraneous load is high, the working memory capacity is overwhelmed, leaving insufficient resources for germane processing. Therefore, effective teaching strategies focus on minimizing extraneous load while encouraging germane load, thereby facilitating deeper comprehension and retention.
