The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, instructional designers often aim to manage cognitive load to optimize learning. According to cognitive load theory, learning is hindered when the intrinsic complexity of the material, combined with the way it is presented, exceeds the learner's available working memory capacity. To mitigate this, experts recommend segmenting complex information into smaller, coherent chunks, and using multiple modalities (e.g., visual and auditory) to reduce extraneous load. However, recent studies suggest that while these strategies are effective for novice learners, they may have diminishing returns for experts, who benefit from more integrated and less scaffolded presentations. This highlights the need for adaptive instructional approaches that consider the learner's prior knowledge and expertise level.
❓ What is the main implication of the research mentioned in the passage?
A. A) Instructional strategies should be uniformly applied to all learners.
B. B) Reducing cognitive load is always beneficial regardless of learner expertise.
C. C) The effectiveness of cognitive load management depends on the learner's level of knowledge.
D. D) Experts require more scaffolding than novices to learn effectively.
✅ 正确答案
C) The effectiveness of cognitive load management depends on the learner's level of knowledge.
