The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, instructional design aims to manage this load to optimize learning. According to Sweller's cognitive load theory, learning is hampered when the load exceeds the learner's cognitive capacity. This can occur when information is presented in a complex or disorganized manner, or when the learner must process multiple interacting elements simultaneously. Strategies such as segmenting information, using worked examples, and reducing extraneous content have been shown to alleviate excessive load. However, recent studies suggest that a certain level of desirable difficulty, or productive struggle, may enhance long-term retention, challenging the notion that cognitive load should always be minimized. Thus, effective instruction may require a balance between reducing unnecessary load and introducing challenges that promote deeper processing.
❓ 文章によると、認知負荷理論に関する最近の研究の主な含意は何ですか？
A. 認知的負荷は、最適な学習を確保するために常に最小限に抑えるべきである。
B. B) ある程度の難しさを取り入れることで長期的な記憶が向上する可能性があるため、負荷を最小限に抑えることが常に理想的とは限らない。
C. C) 実例を示すことは認知的負荷を増大させるため、効果的ではない。
D. D) 認知負荷理論は、最近の研究によって完全に否定されている。
✅ 正确答案
B) Introducing some level of difficulty may improve long-term memory, so minimizing load is not always ideal.
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)
Manage time: about 20 minutes per passage; skip difficult questions first
