The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational contexts, instructional design aims to manage this load to optimize learning. According to cognitive load theory, learning is hampered when the working memory is overloaded with extraneous information that does not contribute to schema acquisition. However, intrinsic load, which is inherent to the complexity of the material, cannot be reduced without simplifying the content itself. Effective instructional methods, such as worked examples and split-attention formats, are designed to reduce extraneous load, thereby freeing resources for the processing of intrinsic load and the construction of mental schemas. This theory has significant implications for the design of multimedia learning environments, where the integration of visual and auditory information must be carefully structured to avoid overwhelming the learner.

D. To eliminate the need for working memory in learning
✅ 正确答案
To reduce extraneous cognitive load and facilitate schema construction
