The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. According to cognitive load theory, instructional design can significantly impact learning efficiency. When information is presented in a complex or disorganized manner, learners experience a high intrinsic load, which may hinder their ability to process new material. However, by using techniques such as segmenting information into smaller chunks or providing worked examples, educators can reduce extraneous load, thereby freeing cognitive resources for deeper understanding. Recent studies suggest that adaptive learning systems, which tailor content to individual learner's needs, are particularly effective in managing cognitive load because they adjust task difficulty in real time, preventing both overload and underload. This dynamic approach not only enhances knowledge retention but also promotes the development of problem-solving skills, as learners are challenged at an optimal level of difficulty.

C. Proporcionan más información que los métodos tradicionales para mejorar el aprendizaje.
D. Se centran únicamente en reducir la carga intrínseca sin considerar la carga extrínseca.
✅ 正确答案
They adjust task difficulty in real time to prevent overload or underload.
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
