“位置法”记忆训练对改善儿童至老年时期的认知功能研究

本工作采用“位置法”对118例被试(包括儿童、少年、青年、中年和老年五个年龄组)进行记忆训练研究,分析不同年龄人记忆的发展变化和认知训练对改善记忆的作用,进而探讨发展的认知功能储备能量的年龄差异。结果表明:1.老年和儿童组各项成绩明显低于青、少年组;2.认知干预措施可在一定程度上改善老年人的记忆,再次证明老年智力和记忆有一定的可塑性。但在发展的储备能量和对图形的迁移效应中也存在与记忆相似的年龄差异。     

Marketing measurably effective instructional methods

The failure to gain wider acceptance of measurably effective teaching methods by the educational establishment may be due to resistance to behaviorism, in particular, and to a set of contingencies that resist change, in general. The promotion of effective instructional methods is presented in terms of recommended marketing principles, including identifying and solving perceived consumer needs, using plain English, segmenting the marketplace and developing specific solutions, identifying opportunities for greatest impact, creating tangible educational products, seeking new markets, planning marketing strategy and tactics, and writing for non-technical publications. Precision Teaching is presented as a case study in the promotion of effective instructional methods. Although it is a measurably superior instructional methodology, Precision Teaching has not been widely adopted. By applying basic marketing principles and strategic planning, some of its proponents have initiated an ongoing effort of outreach and promotion.     

Toward a Renewed Theological Culture: Introduction

This article introduces a series of articles analysing the current state of theology and inquiring about the possibilities of a renewed theological culture (not least within secular societies). It places theology, and more precisely, the conditions of a possible renewal thereof, in several fields of tension. Paradigmatic for secular societies is the tension between theology and the natural sciences. It is argued that theology and the natural sciences cultivate different modes of reasoning on different epistemic levels and that no competition between them has to be construed if one is not caught up in the premises of secularism. A brief summary of each of the contributions follows these initial remarks.     

A qualitative study of the therapists' experiences of working with community reinforcement and family training

Community reinforcement and family training (CRAFT) was developed to help and support concerned significant others (CSO) of people with, for example, alcohol use disorder. The aim of this study was to investigate therapists' experiences of working with CRAFT and their experiences of the CSOs receiving CRAFT. The study has a qualitative design and is based on three focus group interviews with 17 therapists. Interviews were analysed using thematic analysis. The analysis revealed six themes and four subthemes: Concerned significant others—A special group; Help prior to CRAFT—Offering information and a shoulder; CRAFT as a new and specific method (The toolbox of CRAFT, Formats for delivering CRAFT, Introducing a diary as homework and Implementing self-help material—Alone or in combination with sessions); Moving from a lack of structure to structure; Change in CSOs from the therapists' point of view; and Change in the therapist's role (Dilemmas—Personalising the intervention). The therapists were generally satisfied with the method and found it easy to adapt to. Moreover, working using a manual was more structured than they were used to and increased feelings of working professionally with the CSOs. Specifically, most therapists found the self-help book useful and indispensable in their work with CRAFT, but also agreed that it could not be used as a stand-alone intervention for most CSOs. The therapists' experiences are relevant for implementation of manualised, structured approaches and group-based interventions more broadly.     

Argumentation,Adversariality, and Social Norms

Janice Moulton's “The Adversary Method: A Philosophical Paradigm” articulated several criticisms of the popular idea of philosophy as adversarial debate. Moulton criticizes it on epistemic grounds, arguing that philosophy's overreliance on adversarial debate is to the detriment of its goals. Some, notably Trudy Govier, have argued in favor of at least a minimal adversariality, governed by norms of respectful argumentation. This paper suggests that Govier's faith in these norms is misplaced, because it neglects the social circumstances of the arguers. While some authors have argued that politeness and aggression apply differently to those of different genders, this paper extends that analysis to social identities other than gender. In fact, given certain assumptions about the philosophy of language, engagement in polite adversarial debate may not even be possible for people occupying certain social locations.     

基于基尼指数的双目标CD-CAT选题策略

双目标CD-CAT的测验结果既可用于形成性评估也可用于终结性评估。基尼指数可度量随机变量的不确定性程度, 值越小则随机变量的不确定程度越低。本文用基尼指数度量被试知识状态类别以及能力估计置信区间后验概率的变化, 提出基于基尼指数的选题策略。Monte Carlo实验表明与已有的选题策略相比, 新策略的知识状态分类精度和能力估计精度都较高, 同时能有效兼顾题库利用均匀性, 并能快速实时响应, 且受认知诊断模型和被试知识状态分布的影响较小, 可用于实际测验中含多种认知诊断模型的混合题库。     

A driving simulation study to investigate the information threshold of graphical variable message signs based on visual perception characteristics of drivers

Graphical variable message signs (VMSs) are infrastructure-based advanced traveler information systems widely used to provide drivers with real-time traffic condition information about a road section or area. However, there is a lack of research on the suitable volume of information to be shown on graphical VMSs. In practice, an overload of VMS information commonly exists, especially on China’s highways. Building on our earlier findings obtained through surveys and static cognitive experiments, this study introduces the use of dynamic simulation experiments to assess the influence of the volume of information (i.e., number of roads displayed) on graphical VMSs from the perspective of drivers’ visual perception characteristics. Thirty-two drivers participated in the driving simulation experiment and questionnaires. Five indexes, including legibility speed, legibility distance, legibility time, comprehension accuracy, and driver subjective scoring, were thoroughly analyzed to evaluate their relationships to different volumes of information (i.e., four, five, and six roads shown on a VMS). The results show that the legibility distance notably decreased with increasing volumes of information. The comprehension accuracy decreased significantly when the number of roads shown increased to six. The legibility speed, legibility time, and subjective scoring also deteriorated as the number of roads displayed on the VMS increased. The index scores were evaluated, in combination with the data of the drivers’ subjective scoring, data-based statistical analyses, and comprehensive evaluations using the TOPSIS method, to recommend that five is the recommended maximum number of roads to be shown on a graphical VMS. The results of this study support the goal of providing understandable and effective messages for drivers by addressing issues relating to how much information should be displayed on a VMS. These findings provide a basis for policy development to ensure consistent and practical designs of graphical VMSs on highways.     

La méthode d’intervention en psychodynamique du travail face au « tournant gestionnaire » : l’exemple d’une intervention dans une unité mixte de recherche

This text aims to show the continuing interest in using the “canonical” method of investigation in work psychodynamics in the context of what is commonly called the managerial turning point. In order to demonstrate this methodology, the authors will rely on a survey conducted in a U.M.R of science called “hard science” following a recommendation of the Agency for evaluation of research and higher education. We will raise the impact of this intervention, allowing participants to think about their work relationship and the necessary modalities in order to do it continuously well, within the managerial logic context.     

Bootstrap区间估计在认知诊断模型误设中的应用

认知诊断模型选择是认知诊断评估中重要研究问题之一。在实际应用中实践者并不知道真正拟合数据的模型,通常会用模型拟合指标检验模型与数据的拟合程度。从测量结果质量来看,除保证模型与数据拟合之外,还需要重点评价模型诊断结果的信度和效度等。考虑到以往研究大都采用基于信息量的拟合指标去判定模型与数据的匹配性,本研究提出综合考虑模型拟合指标与信度指标用于模型选择或评价模型误设。考虑实验因素为真实模型或分析模型（DINA模型、G-DINA模型、R-RUM模型）、样本量、题量和属性个数,在五因素（3×3×2×2×2）实验设计条件下,比较Bootstrap区间估计的属性分类一致性信度平均数与标准误和常用的拟合统计量-2LL、AIC、BIC对正确模型的选择率。结果表明：-2LL在题目数量多的情况下表现较好,而AIC、BIC在被试量较大的情况下表现较好,在不同的研究条件下,-2LL、AIC、BIC的模型选择率很不稳定,而用Bootstrap法估计的属性分类一致性信度平均数和标准误在不同研究条件的模型选择率较稳定,总体表现较好。     

翻转教学法对高中生认知负荷及学习成绩的影响

采用不等组实验组、控制组前测后测的准实验设计,探讨了翻转课堂背景下翻转教学法对高中生认知负荷及学习成绩的影响。结果发现：（1）翻转教学法能有效降低高中生的内在认知负荷,提高其学习成绩与学习效率;（2）翻转课堂背景下,高中生的认知负荷存在知识反转效应,即高成绩者的收益低于低成绩者。结果提示,翻转课堂取得优异学习效果的心理机制在于通过有效降低学习者的内在认知负荷而影响其学习成绩;同时,翻转教学法的运用过程中须考虑学习者认知负荷的变化及学习效率,其对所有的学习者不是同等有效的。
