📖 Reading Passage

The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational psychology, cognitive load theory suggests that instructional design should minimize extraneous cognitive load to facilitate learning. Extraneous load is generated by the way information is presented, such as unnecessary distractions or complex formatting, which does not contribute to schema construction. Intrinsic load, on the other hand, is inherent to the complexity of the material itself and cannot be altered by instruction. Germane load, the third type, is the effort devoted to processing and understanding the material, leading to the creation of schemas. Effective teaching strategies aim to manage intrinsic load, reduce extraneous load, and promote germane load. For instance, using worked examples can reduce extraneous load by providing clear problem-solving steps, allowing learners to focus on underlying principles.
