基于选项层面的认知诊断非参数方法

充分挖掘选择题(Multiple-Choice, MC)的诊断信息受到了较多关注, 将干扰项信息考虑在内可以提升诊断精度。为了弥补参数模型基于大样本才能获得可靠估计的不足, 以及适用于班级水平的小样本诊断测验情境, 本研究提出了非参数的多选题诊断方法。模拟和实证研结果表明：(1)当MC测验中题目参数不存在较大差异时, ${{d}_{\text{ph}-\text{MC}}}$法在多数情况下表现优于参数类诊断模型。(2)当MC测验中题目参数存在较大差异时, ${{d}_{ph-MC}}$法的表现最优。(3)实证研究中非参数方法和参数类模型的分类一致性程度较高, ${{d}_{\text{ph}-\text{MC}}}$距离法估计得到的考生属性总体掌握程度与总分相关最高。最后, 基于MC诊断测验的特点提出了若干研究方向。     

La méthode agile,une nouvelle méthode pour promouvoir l’accompagnement inclusif

Over the past fifteen years, the health and social care policies in charge of vulnerable population, have evolved and have urged professionals to change their practices to promote the values of an inclusive society. Personal support has reached a consensus in response to fostering empowerment and coordinating efforts for actions undertaken. However, for lack of new methods capable of shaping outreach differently, practices are struggling to free themselves from phased management processes organized on a logic of support. This article aims at presenting an original method called “agile” that meets current expectations. It is based on six principles of action guaranteeing not only mobility and resources of the situation but also the empowerment of the accompanying and the accompanied.     

Knowledge and assertion in “Gettier” cases

Assertion is fundamental to our lives as social and cognitive beings. By asserting, we share knowledge, coordinate behavior, and advance collective inquiry. Accordingly, assertion is of considerable interest to cognitive scientists, social scientists, and philosophers. This paper advances our understanding of the norm of assertion. Prior evidence suggests that knowledge is the norm of assertion, a view known as “the knowledge account.” In its strongest form, the knowledge account says that knowledge is both necessary and sufficient for assertability: you should make an assertion if and only if you know that it is true. The knowledge account has been rejected on the grounds that it conflicts with our ordinary practice of evaluating assertions. This paper reports four experiments that address an important objection of this sort, which focuses on a class of examples known as “Gettier cases.” The results undermine the objection and, in the process, provide further evidence for the knowledge account. The findings also teach some important general lessons about intuitional methodology and the curation of genres of thought experiment.     

顿悟体验的心理与神经机制

顿悟体验研究是揭示顿悟本质的重要途径。先前研究从认知角度对顿悟问题解决中的"旧而无效解题思路如何抛弃"与"新而有效解题思路如何形成"过程进行了颇多探讨,但较少探讨顿悟体验本身。顿悟体验研究对理清创造性顿悟中关键过程间的关系及阐明顿悟的科学规律均有重要的意义。基于创造性顿悟的"新旧交替"的动态视角,本项目拟借助多元方法来对言语类和视图类问题解决过程中尝试解题阶段和答案闪现阶段的顿悟体验的心理实质与脑机制进行研究。本项目成果不仅可以丰富和优化顿悟问题研究的方法学体系,而且能从知情转化层面深化对创造性顿悟脑机制的认识。     

一种可融入额外信息的机器学习诊断法

研究将PNN和曼哈顿距离、贝叶斯定理相结合,提出了一种相对简洁的可融入额外信息的认知诊断法MB-PNN,通过模拟和实证研究考察了MB-PNN的有效性和适宜性,得到以下结论:(1)M-PNN的判准率高于PNN,表明将PNN中的ED修改为MD是适宜的;(2)MB-PNN的判准率较M-PNN和PNN高,表明基于多种信息的判别较基于单一信息的判别更为精准;(3)MB-PNN保留了PNN原有的非参数优势,基本不受知识状态分布和样本容量影响;(4)MB-PNN最能区分不同类型的学生,在认知诊断评估实践中更为适宜。     

基于CAT的在线标定:设计与方法

项目增补是题库建设和维护的重要手段, 而标定新题参数是项目增补的重要内容。在线标定设计和在线标定方法分别研究新题的施测方式和参数估计方法, 是计算机化自适应测验(computerized adaptive testing, CAT)情景下项目增补的核心技术。重点厘清在线标定设计与在线标定方法的发展思路和脉络, 并对它们的特点、联系和表现进行介绍和评价。未来应基于其他信息指标进一步研究在线标定设计, 可基于联合估计和误差校正的思路探究在线标定方法, 应加强研究认知诊断CAT和多维CAT的在线标定技术, 深入开展项目增补方法的实证研究。     

An interactive procedure for learning about preferences: Case study of a portfolio manager

This paper presents a new interactive procedure for learning and interpreting the choices available to a decision maker confronted with a discrete decision problem. The procedure guides a decision maker through the evaluation process, has an ability ‘to learn’ from previous choices and generates a set of rules that describe a decision maker's posterior preferences. The validity of the procedure was tested by creating an investment portfolio. The emphasis of the application is on assisting the portfolio manager to determine the decision consistency of a given portfolio selection process.     

关键字母法对于英文词汇记忆作用的实验研究

本研究以大学生为被试,以英文单词为实验材料,采用实验室实验法,探讨了关键字母法对于英文词汇记忆的作用。研究结果表明：无论从即时测验的成绩来看,还是从延迟测验的成绩来看,标准关键字母法都能够促进英文词汇的记忆。     

Theology: Reduction or Autonomy?

Issues of the nature and task of theology remain important to the science-theology dialogue. This paper lays out a framework for understanding the nature of theology in relation to the other sciences. In particular, I argue that the primary question remains one of autonomy and reduction. If theology is a genuine academic discipline, then it should be an autonomous field with its own subject matter and norms. Wolfhart Pannenberg argues that theology is the science of God, but I suggest that theology be more broadly understood as the science of meaning. If we recognize this, the modes of interaction between theology and the other sciences becomes clearer.
