📖 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 material itself, which cannot be altered by instructional design. Extraneous load is generated by the way information is presented to the learner, such as confusing diagrams or unnecessary text, and can be minimized through better design. Germane load, on the other hand, is the effort devoted to processing and understanding the material, which is beneficial for learning. Research suggests that effective instructional strategies aim to reduce extraneous load while optimizing germane load, thereby facilitating deeper learning without overwhelming the learner's cognitive capacity.
