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 cognitive load theory, learning is hindered when the intrinsic complexity of the material, the way it is presented, and the effort required to process it exceed the learner's capacity. Effective strategies include breaking complex tasks into smaller steps, using worked examples, and reducing extraneous information. However, researchers debate whether these techniques are universally beneficial, as individual differences in prior knowledge and working memory capacity can influence outcomes. A recent meta-analysis found that while reducing extraneous load generally improves performance for novices, it may have little effect for experts who can rely on existing schemas. Thus, adaptive instructional approaches may be necessary to cater to diverse learners.

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
