以实质心理学为基础的评估：认知诊断

评价除了了解学习者的学习情况外,同时还应该提供学习者学习状况的诊断信息,以利于教学与学习。评价应该以认知心理学对学习过程的研究,作为编制测验的实质理论依据,进行认知诊断评估。本文针对认知诊断的心理学基础：知识的习得、知识诱发、知识表征、知识结构等进行梳理,以便测验开发者对认知诊断评估有更清晰的认识。     

Stories as indicators of practical knowledge: Analysing project workers' talk from a study of participation in a youth inclusion programme

The paper deals with the issue of practical knowledge for enabling participation. Participation as a strategy for change is widespread in community, health and human service contexts. Research to date has focused on the mechanisms of beneficiaries' participation (e.g. identity, empowerment, activity, gender, space). However, participation as an engagement strategy is action oriented and requires high levels of interaction between those creating the conditions for participation and those participating. These conditions need to be continuously adjusted and outcomes are often unpredictable. This process of ‘working with’ is often dealt with as a technical issue and captured in metaphorical language. Less emphasis has been given to the type of knowledge modalities that might be necessary in order to enable participation. Drawing on an ethnographic case study of participation in a youth inclusion programme the paper explores the role of stories as potential indicators of practical knowledge. The paper argues that enabling young people's participation requires intuition and imagination, patience and perseverance, and judgement for acting under uncertainty. It concludes that stories only partially fulfil their potential as indicators of such knowledge modalities. Copyright © 2010 John Wiley & Sons, Ltd.     

Levels of modality for BDI Logic

The use of rational agents for modelling real world problems has both been heavily investigated and become well accepted, with BDI (Beliefs, Desires, and Intentions) Logic being a widely used architecture to represent and reason about rational agency. However, in the real world, we often have to deal with different levels of confidence in the beliefs we hold, desires we have, and intentions that we commit to. This paper extends our previous framework that integrated qualitative levels of beliefs, desires, and intentions into BDI Logic. We describe an expanded set of axioms and properties of the extended logic. We present a modular structure for the semantics which involves a non-normal Kripke type semantics that may be used for other agent systems. Further, we demonstrate the usefulness of our framework with a scheduling task example.     

学科领域知识丰富性对中学代数问题表征层次的影响

研究学科领域知识丰富性不同的学生在问题表征过程中信息表征层次的特点。采用“学习-再认”范式,以5类等式为材料,62名初二学生参与实验。结果：两组被试对表面和原理特征一致的等式产生明显的错误再认;对表面特征不一致等式的错误率明显减少。无论原理特征是否一致,两组对表面特征一致等式的反应时无显著差别,但在正确率上丰富组的更高。说明,两组均以有序的系列加工方式编码信息,优先编码表面特征。贫乏组对原理特征的编码干扰表面特征的加工,因而原理特征被丢弃。丰富组加工表面特征则无干扰现象出现,两种特征均能作为再认线索。     

词汇语音学习的影响因素

摘要 词汇语音的学习受哪些因素的影响是心理语言学研究中一个重要的问题。语音回路理论认为,语音短时记忆在词汇语音的学习过程中发挥着关键性的作用,语音短时记忆能力越好越有助于词汇的学习;语音敏感性假说认为,语音意识是影响儿童词汇发展及学习的重要因素;另外一些研究者认为,语音知识可能发挥着更为基础和关键的作用,最近的研究则更加强调几种因素如何相互作用影响词汇语音的学习。本文最后提出了该领域需要进一步研究的问题。     

高校教师知识共享态度的相关研究

以151名高校教师为测查对象,采用“高校教师知识共享问卷”等研究工具,考察工作态度、组织特征等因素与高校教师知识共享态度之间的关系.结果发现:(1)文、理科教师之间在避损性共享和人际性共享上存在显著差异;(2)组织认同、工作满意度、知识特性和学科与避损性共享存在显著相关;(3)组织认同、工作满意度、工作意义、工作奉献、组织特性和学科与人际性共享存在显著相关.研究表明,理科教师的共享态度较文科教师更为积极;知识共享除了与工作态度有关之外,也与软硬件环境有关.     

国内元认知的相关研究及其展望

元认知这一概念是由美国发展心理学家弗莱维尔(Flavell)在1976年正式提出来的。至今,学者们对其进行了广泛深入的研究,无论是在理论还是实证方面都取得了丰硕的成果。文章首先对元认知(metacognition)的概念作了阐述,接着陈述了当前关于元认知的结构比较认可的两分法以及三分法,并提出了关于元认知结构的看法。然后对目前国内元认知的相关研究做一综述,最后文章在分析过去研究所存在问题的基础上提出了对元认知研究的展望。     

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。     

Event completion: event based inferences distort memory in a matter of seconds

We present novel evidence that implicit causal inferences distort memory for events only seconds after viewing. Adults watched videos of someone launching (or throwing) an object. However, the videos omitted the moment of contact (or release). Subjects falsely reported seeing the moment of contact when it was implied by subsequent footage but did not do so when the contact was not implied. Causal implications were disrupted either by replacing the resulting flight of the ball with irrelevant video or by scrambling event segments. Subjects in the different causal implication conditions did not differ on false alarms for other moments of the event, nor did they differ in general recognition accuracy. These results suggest that as people perceive events, they generate rapid conceptual interpretations that can have a powerful effect on how events are remembered.     

The mental representation of causal conditional reasoning: mental models or causal models

In this paper, two experiments are reported investigating the nature of the cognitive representations underlying causal conditional reasoning performance. The predictions of causal and logical interpretations of the conditional diverge sharply when inferences involving pairs of conditionals—such as if P₁then Q and if P₂then Q—are considered. From a causal perspective, the causal direction of these conditionals is critical: are the P_icauses of Q; or symptoms caused byQ. The rich variety of inference patterns can naturally be modelled by Bayesian networks. A pair of causal conditionals where Q is an effect corresponds to a “collider” structure where the two causes (P_i) converge on a common effect. In contrast, a pair of causal conditionals where Q is a cause corresponds to a network where two effects (P_i) diverge from a common cause. Very different predictions are made by fully explicit or initial mental models interpretations. These predictions were tested in two experiments, each of which yielded data most consistent with causal model theory, rather than with mental models.
