The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational psychology, cognitive load theory suggests that learning is most effective when instructional materials are designed to minimize extraneous cognitive load, allowing learners to devote their full mental capacity to the essential processing of new information. Research has shown that when learners are presented with redundant or overly complex information, their working memory becomes overloaded, hindering the transfer of knowledge to long-term memory. Conversely, well-structured materials that integrate visual and verbal information spatially and temporally can reduce cognitive load and enhance learning outcomes. This theory has significant implications for curriculum design, particularly in multimedia learning environments where the potential for split-attention effects is high.

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)
