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.
❓ Согласно тексту, каково основное значение недавних исследований теории когнитивной нагрузки?
A. A) Когнитивная нагрузка всегда должна быть минимизирована для обеспечения оптимального обучения.
B. B) Введение некоторого уровня сложности может улучшить долговременную память, поэтому минимизация нагрузки не всегда идеальна.
C. C) Разобранные примеры неэффективны, поскольку они увеличивают когнитивную нагрузку.
D. D) Теория когнитивной нагрузки была полностью опровергнута недавними исследованиями.
✅ 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
