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 reduce extraneous cognitive load, thereby freeing resources for the intrinsic load necessary for understanding complex material. This theory has significant implications for multimedia learning, where the presentation of information through both auditory and visual channels can either enhance or impede comprehension. For instance, when a diagram is accompanied by redundant on-screen text, learners may experience split attention, increasing extraneous load. Conversely, integrating labels directly onto the diagram can reduce this burden. However, experts argue that the optimal level of cognitive load varies with the learner's prior knowledge, making a one-size-fits-all approach inadequate.
❓ ¿Cuál es una implicación clave de la teoría de la carga cognitiva para el diseño instruccional?
A. A) Maximizar la cantidad de información presentada simultáneamente en formatos tanto visuales como auditivos.
B. B) Para minimizar la carga cognitiva extrínseca evitando presentaciones redundantes que provoquen atención dividida.
C. C) Para garantizar que todos los aprendices experimenten el mismo nivel de carga cognitiva, independientemente de su nivel de experiencia.
D. D) Eliminar toda la carga cognitiva intrínseca para que el aprendizaje se vuelva sin esfuerzo para los principiantes.
✅ 正确答案
B) To minimize extraneous cognitive load by avoiding redundant presentations that cause split attention.
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
