Young Children's Reports of When Events Occurred: Do Event Type and Assessment Method Matter?

Studying young children's reporting about when various events occurred informs about the development of episodic memory and metacognition. In two experiments, 55 3‐ to 5‐year‐old children participated in two activity sessions, a week apart. During the activity sessions, they learned novel animal facts and body movements, and they coloured animal pictures and posed for body movement photos. Immediately after the second activity session, children were interviewed about when they experienced the various events. Overall, children were as accurate about learning events as physical events, but they were more accurate when asked temporal distance (e.g. ‘Which did you learn a longer time ago, “X” or “Y”?’) than temporal location questions (e.g. ‘Which did you learn before today, “X” or “Y”?’). The results suggest that young children's apparent difficulty recognizing new learning is not due to a rapid ‘remember‐to‐know shift’. Rather, the way we ask young children about when they experienced various events determines their accuracy. Copyright © 2016 John Wiley & Sons, Ltd.     

儿童计算的元认知监测及其对策略选择的影响

为了考察儿童在计算中的元认知监测及其对策略选择的影响,选用两种实验材料,对五种元认知监测判断的特点及监测判断对策略选择的影响进行考察,发现:儿童的元认知监测判断等级值总体上具有较高的一致性,元认知监测判断大多与策略选择高度相关,具有较好的预测力,但受材料、指导语等因素影响,又呈现出复杂的关系。本研究从一个侧面证实了元认知监控的基本假说和元认知监测判断的状态说。     

元认知训练的动机增强效应

如何激发学习动机是当前教育工作者、心理学研究者都很关注的一个问题。干预动机变量已经被证明是一种可行的方法,我们认为,认知干预也是激发学习动机的一种有效途径。为了检验这一假设,本研究对47名初二学生进行为期三周的数学元认知训练。差异显著性检验表明,在元认知训练中,被试的动机和元认知都有一定改善;路径分析进一步表明,元认知的改善导致了动机的改善。这一结论为动机激发这一现实问题提供了一条新思路,并且使我们对于元认知与动机的关系形成了更为全面的认识。     

幼儿元认知知识发展的特点

以北京市某幼儿园5个班98名幼儿为被试,利用分类和拼图任务对其元认知知识进行了测试.结果发现:3～5岁幼儿在元认知知识的某些方面表现出了一定的发展变化过程,对主体性的元认知知识、任务难度的元认知知识和策略的元认知知识的认识表现出了显著的年龄差异,特别是内部策略的运用随着年龄的增长越来越多,而对外部策略的运用越来越少.

高中生数学元认知水平调查问卷的设计与编制*

对于元认知能力的评价和测试一直以来都是研究的难点,特别是就数学学科而言,已有研究多围绕数学问题解决过程中元认知监控水平的评价以及能力的培养展开,鲜有全面评价学生数学学习元认知水平的问卷。同时,没有针对高中生编制的元认知水平调查问卷。故本研究在已有研究的基础上,对已有的问卷进行修正和完善,通过征求专家意见与样本测试和数据分析,形成《高中生数学元认知水平调查问卷》。该问卷具有较好的内容效度和结构效度。信度方面,问卷整体的内部信度为0.952,分半信度为0.931,重测信度为0.946,说明问卷具有很好的内部一致性和测量稳定性。     

论元认知和智力的相互关系

元认知水平与智力活动之间关系密切。元认知由三部分组成：元认知知识、元认知体验和元认知技能,它与智力中的元成分、操作成分和知识获得成分密切相关。人知在人类智力因素中占有重要作用,是智力活动中的核心因素之一。智力也会影响元认知活动。它们之间相互影响、相互作用。     

Metacognitive Judgments and Control of Study

ABSTRACT— Recent evidence indicates that people's judgments of their own learning are causally related to their study behavior and not epiphenomenal. I argue here that people use these metacognitions in an effort to selectively study material in their own region of proximal learning. First they attempt to eliminate materials that are already well learned. Then they progress successively from studying easier to more difficult materials. Successful implementation of this metacognitively guided strategy enhances learning. The necessary components are, first, that the metacognitions be accurate, and second, that the appropriate choices are implemented for study. With these parts in place, the individual is in position to effectively take control of his or her own learning.     

Metacognitive Experiences and Human Judgment: The Case of Hindsight Bias and Its Debiasing

ABSTRACT— Theories of judgment have emphasized the influence of what comes to mind—the content of people's thoughts. But recent research shows that metacognitive experiences accompanying thinking, like a sense of the ease or difficulty with which information comes to mind, qualify the conclusions that people derive from thought content. The case of hindsight bias and attempts to remove that bias (debiasing) illustrate this. After an event outcome is known, people display hindsight bias by exaggerating its inevitability, believing they "knew it all along." The magnitude of hindsight bias varies with the ease or difficulty that known or alternative outcomes come to mind; the usually observed hindsight bias may even reverse when outcomes are difficult to bring to mind or increase when alternatives are difficult to bring to mind. Implications of metacognitive experiences can extend to other biases and their debiasing, as well as to how people make sense of the past more generally.     

问题解决策略的元认知研究

本研究旨在了解大学生对问题解决策略的理解。通过测试57名大学生对五种问题解决策略(自由产生、类推、逐步分析、形象化重构和整合)在三种情景(人际交往、实际生活和学习过程)三个维度(经常使用、有效性、易于使用)下的评估,发现大学生使用类推策略最多,自由产生策略最少。他们普遍认为这五种策略最适宜于用在学习情景中,在人际交往中的用处不大。这种结果在性别上没有显著性差异。另外．大学生认为几乎每一种策略都需要综合、分析、判断和推理四种思维能力,其中自由产生策略需要用到更多的能力,包括创造能力。     

The Effect of a Computerized Decision Aid on the Development of Knowledge

This study provides evidence on how the use of a computerized decision aid affects knowledge acquisition. While the intent of such computer-based decision aids is to improve and support unaided human judgments, it is unclear whether the use of the aids actually facilitate knowledge transfer. Seventy-six subjects completed a hypothetical decision task where one of two types of decision aids was used: an expert system or traditional textual materials. Results suggest that those using a computer-based decision aid acquired and encoded in memory less declarative knowledge than those using textual reference materials. Implications of the findings are discussed.     

Discrimination in measures of knowledge monitoring accuracy

Knowledge monitoring predicts academic outcomes in many contexts. However, measures of knowledge monitoring accuracy are often incomplete. In the current study, a measure of students’ ability to discriminate known from unknown information as a component of knowledge monitoring was considered. Undergraduate students’ knowledge monitoring accuracy was assessed and used to predict final exam scores in a specific course. It was found that gamma, a measure commonly used as the measure of knowledge monitoring accuracy, accounted for a small, but significant amount of variance in academic performance whereas the discrimination and bias indexes combined to account for a greater amount of variance in academic performance.     

Six Years in the Cognitive and Metacognitive Life of 71 Families

Seventy-one families from a low socio-economic background, each with a son at risk of developing psychosocial problems at the onset of the study, were observed three times over a six-year period while solving a combinatorial task presented on a microcomputer. The permutations task was used to gather information with regard to cognitive functioning and cognitive self-regulation of the families, which were observed as a developmental unit. Cognitive functioning was assessed according to three variables: cognitive strategies, performance, and completion of the task. Six self-regulatory activities were assessed: task definition, planning, supervision, evaluation, parental support, and sharing of responsibilities. Although inefficient strategies were mainly used across the six years, the cognitive level of functioning improved over the years. Cognitive self-regulatory activities most often used across time were supervision and parental support. Differences were observed in the three time periods for supervision, task definition, parental support, and individual involvement. Results indicated a link between cognitive strategies used by the families to solve the task and their self-regulatory activities. Results are interpreted within both the Piagetian and Vygotskian perspectives. Families' cognitive self-regulatory activities observed in this study are an example of parental disengagement and children's growing involvement in a joint activity.     

广东省城乡初中生元认知水平比较研究

研究采用自编问卷和访谈法对城乡初中生进行元认知水平的对比研究,结果表明：1）城乡初中生元认知水平总体差异显著,农村初中生的元认知水平总体低于城市初中生的元认知水平。2）城乡初中生在认知前元认知体验和认知中元认知知识维度上差异显著。认知前元认知知识、认知中元认知体验、认知后元认知知识、认知后元认知体验之间无显著性差异。建议加强教师和学生元认知训练,提高学生元认知水平。     

浅谈元认知知识的培养及其评定

元认知知识是元认知的主要成份之一,它由三部分知识组成:认知主体方面的知识、认知任务方面的知识和认知策略方面的知识。在教学过程中加强对学生元认知知识的培养与训练,有利于学生学会学习,从而达到最佳的学习效果。元认知知识的评定难以在大规模考试中实现,应该综合运用多种方法在日常教学中加以评定,并作为主要任务之一纳入学生的形成性评价。
