The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, instructional designers often strive to manage cognitive load to optimize learning. According to Sweller's cognitive load theory, learning is hindered when the intrinsic load (complexity of the material) and extraneous load (how the material is presented) exceed the learner's capacity. For instance, a poorly designed diagram may force students to split their attention between multiple sources of information, thereby increasing extraneous load. Conversely, integrating text and graphics can reduce this load, freeing resources for schema construction. Recent studies suggest that adaptive learning technologies, which tailor content to individual proficiency levels, can effectively regulate intrinsic load by breaking down complex problems into manageable steps. However, critics argue that over-simplification might reduce the depth of processing necessary for long-term retention, indicating a delicate balance between support and challenge.

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
