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 learning is most effective when instructional materials are designed to reduce extraneous load, which is unnecessary mental effort caused by poor presentation. For instance, when a diagram is accompanied by redundant text, learners may split their attention between the two sources, increasing extraneous load. However, intrinsic load, which is inherent to the complexity of the subject matter, cannot be eliminated. Effective teaching strategies often aim to manage intrinsic load by breaking down complex tasks into smaller, sequential steps. Recent studies have shown that optimizing cognitive load can significantly improve problem-solving performance, especially in STEM fields where abstract concepts are prevalent.
❓ According to the passage, what is the primary difference between extraneous and intrinsic load?
A. Extraneous load is beneficial for learning, while intrinsic load is not.
B. Extraneous load can be reduced by better instructional design, while intrinsic load is inherent to the material.
C. Intrinsic load is caused by poor presentation, while extraneous load is due to task complexity.
D. Both types of load are equally difficult to manage in educational settings.
✅ 正确答案
Extraneous load can be reduced by better instructional design, while intrinsic load is inherent to the material.
