Cognitive Learning01:21

Cognitive Learning

517
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Cognitivism

1.7K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Metacognition01:26

Metacognition

280
Metacognition is a conscious process where individuals are aware of their cognitive and executive processes, such as planning before solving a problem or self-monitoring during reading. For instance, a writer may need help with composing a piece. The situation involves a writer who is working on a piece of writing, but while doing so, they realize that something is missing. They notice that their characters lack depth or details. This realization occurs because the writer is reflecting on their...

Chunking01:12

Chunking

188
Chunking is a powerful cognitive technique that improves short-term memory retention by organizing information into smaller, more manageable units. The brain, limited by working memory capacity, can more easily process and store information when it is divided into "chunks" rather than presented as discrete, unrelated elements. Chunking is especially useful when dealing with large amounts of information, such as numerical sequences, words, or complex ideas.
The principle behind chunking...

Elaborative Rehearsals01:07

Elaborative Rehearsals

130
Elaborative rehearsal is a crucial cognitive strategy that strengthens information encoding in long-term memory by making meaningful connections between new data and pre-existing knowledge. This approach contrasts with maintenance rehearsal, which involves simple repetition without delving into the significance of the information. While maintenance rehearsal might temporarily keep information active in short-term memory, it is less effective for long-term retention.
The effectiveness of...

Working Memory01:24

Working Memory

444
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

科学领域:

  • 认知心理学
  • 教育技术
  • 教学设计

背景情况:

  • 认知负载理论 (CLT) 认为工作记忆的局限性会影响学习.
  • 在学习任务中,先前的知识是影响个体认知负载的关键因素.
  • 专业知识反转效应表明,对新手有效的教学策略可能会阻碍专家.

研究的目的:

  • 在解决问题过程中研究先前知识,预训练和认知负载之间的关系.
  • 确定前期培训是否会降低认知负载,或者对具有高先前知识的学习者来说是多余的.
  • 检查预训练对内在,外在和相关认知负载的影响.

主要方法:

  • 在136名大学生中进行了一项实验.
  • 使用概念地图和术语和程序的词汇表进行了预培训.
  • 在解决问题过程中测量认知负荷.

主要成果:

  • 具有较高先验知识的学习者报告了较低的内在和外部负载,以及较高的外在负载.
  • 预训练显著减少了所有参与者的外在认知负担, 不管他们有没有先前的知识.
  • 没有观察到专业知识反转效应;预培训没有对具有更高先前知识的学习者产生负面影响.

结论:

  • 预训练是一种有价值的教学策略,
  • 在解决问题过程中,学习者的先前知识显著调整了他们的认知负载经验.
  • 教学设计应考虑学习者的现有知识,以优化学习成果并尽量减少认知负担.
