The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, excessive cognitive load can hinder learning, as learners may struggle to process new information when their mental resources are overwhelmed. This phenomenon is particularly evident in complex subjects like mathematics or science, where students must simultaneously grasp abstract principles and apply them to problem-solving. Researchers have proposed various strategies to manage cognitive load, such as segmenting information into smaller chunks, using multimedia to illustrate concepts, and providing worked examples before independent practice. However, recent studies suggest that the effectiveness of these strategies may vary depending on individual differences, such as prior knowledge and learning style. For instance, novices benefit more from worked examples, while experts may find them redundant and prefer open-ended tasks. Thus, educators must tailor their approaches to optimize learning outcomes for diverse student populations.
❓ According to the passage, why might worked examples be less effective for expert learners?
A. A. Experts have already mastered the concepts and may find the examples unnecessary.
B. B. Worked examples increase cognitive load more for experts than for novices.
C. C. Experts prefer to learn from multimedia presentations rather than text-based examples.
D. D. Worked examples are too complex for experts to understand quickly.
✅ 正确答案
A. Experts have already mastered the concepts and may find the examples unnecessary.
