📖 Reading Passage

The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational psychology, it is often divided into three types: intrinsic, extraneous, and germane. Intrinsic load is associated with the inherent difficulty of the subject matter, which cannot be altered by instructional design. Extraneous load is generated by the way information is presented to learners, and can be minimized through effective teaching strategies. Germane load, on the other hand, is the mental resource devoted to processing and understanding the material, which directly contributes to learning. Research suggests that instructional designers should aim to reduce extraneous load while optimizing germane load, thereby facilitating deeper comprehension and retention.
