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 load, which is unnecessary mental effort caused by poor presentation. For instance, when a diagram is accompanied by redundant text, learners may split their attention between the two sources, increasing extraneous load. However, intrinsic load, which is inherent to the complexity of the subject matter, cannot be eliminated. Effective teaching strategies often aim to manage intrinsic load by breaking down complex tasks into smaller, sequential steps. Recent studies have shown that optimizing cognitive load can significantly improve problem-solving performance, especially in STEM fields where abstract concepts are prevalent.
❓ Según el pasaje, ¿cuál es la diferencia principal entre la carga extrínseca y la carga intrínseca?
A. La carga extrínseca es beneficiosa para el aprendizaje, mientras que la carga intrínseca no lo es.
B. La carga extrínseca puede reducirse mediante un mejor diseño instruccional, mientras que la carga intrínseca es inherente al material.
C. La carga intrínseca es causada por una mala presentación, mientras que la carga extrínseca se debe a la complejidad de la tarea.
D. Ambos tipos de carga son igualmente difíciles de manejar en entornos educativos.
✅ 正确答案
Extraneous load can be reduced by better instructional design, while intrinsic load is inherent to the material.
