The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, instructional design often aims to manage cognitive load to optimize learning. According to cognitive load theory, learners have limited working memory capacity, and if the complexity of the material (intrinsic load) is high, additional demands from the way the material is presented (extraneous load) can hinder learning. However, effective design can promote 'germane load', which is the effort devoted to processing and understanding the underlying structure of the content. Recent studies suggest that interactive learning environments, while engaging, may inadvertently increase extraneous load if not carefully structured, thus reducing the potential benefits of active participation.
❓ ¿Cuál es la principal implicación de la teoría de la carga cognitiva para el diseño instruccional?
A. A) Los entornos interactivos siempre deben evitarse para prevenir la sobrecarga de los estudiantes.
B. B) Los diseñadores deben minimizar la carga extrínseca para permitir más capacidad para el procesamiento pertinente.
C. C) La carga intrínseca debería eliminarse para facilitar el aprendizaje de todos los estudiantes.
D. D) La capacidad de la memoria de trabajo puede ampliarse mediante el entrenamiento para manejar más información.
✅ 正确答案
B) Designers should minimize extraneous load to allow more capacity for germane processing.
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
