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, overwhelms the learner's limited working memory capacity. However, by breaking down complex information into smaller, interconnected segments and using visual aids to complement verbal explanations, educators can reduce extraneous load and facilitate schema construction. Recent studies suggest that adaptive learning systems, which tailor the pacing and content based on real-time learner performance, can further mitigate cognitive overload. These systems adjust the difficulty level dynamically, ensuring that learners remain in a state of productive challenge rather than frustration or boredom. Consequently, effective instructional strategies must consider both the nature of the subject matter and the individual differences in working memory capacity.
❓ According to the passage, what is a primary benefit of adaptive learning systems?
A. They eliminate all intrinsic cognitive load for learners.
B. They reduce extraneous cognitive load by simplifying content.
C. They dynamically adjust difficulty to prevent cognitive overload.
D. They replace the need for visual aids in instruction.
✅ 正确答案
They dynamically adjust difficulty to prevent cognitive overload.
IELTS Reading Tips
Skim the questions first, underline keywords, then locate in the passage
Watch for paraphrasing; correct answers are often reworded
Be wary of absolute statements (all, always, never) — usually wrong
Pay attention to content after transition words (however, but, yet)
