阅读中自然学习生词的实验研究

本研究对儿童阅读时从语境中自然学习生词的过程及其多个影响因素进行了探讨。301名三、五年级小学生参加了实验。首先要求他们阅读文章,然后测验他们对文章中生词的知识。本研究在不同年级和能力的儿童中都发现了显著的自然学习效应。结果还表明,词的概念难度、词结构的语义透明度、语境线索强度和儿童课外阅读量对儿童的自然学习有重要影响。     

提取练习在记忆保持与迁移中的优势效应：基于认知负荷理论的解释

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明：(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用：在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。     

Authoritarianism and Political Impoverishment: Deficits in Knowledge and Civic Disinterest

Past research shows that authoritarian individuals hold strong opinions about a variety of political and social issues, such as race relations and military conflict. What has not been established, though, is the amount of general political knowledge that authoritarians possess. In this study, three groups of college students were administered Altemeyer's Right-Wing Authoritarianism (RWA) scale; most of them also received items assessing general political knowledge and specific knowledge about the 2000 presidential election, as well as items assessing interest in politics. Relative to students with low RWA scores, those with high scores possessed less political knowledge; moreover, they expressed less interest in learning about politics. In general, authoritarianism was unrelated to how individuals got their political information or how credible they found their sources. The implication that authoritarians hold strong attitudinal beliefs with weak political knowledge is discussed.     

Introduction: Attaining a New Stage

The current issue of The Journal of Adult Development addresses one of the threads of adult development, namely stage and stage change. There are four major forms of adult developmental study that can be identified: positive adult development, directionless change, stasis, and decline. The first of the four forms, positive adult developmental processes, is divided into at least six areas of study: hierarchical complexity (orders, stages), knowledge, experience, expertise, wisdom, and spirituality. The topic of this special issue, stage and stage change, is therefore part of the study of positive adult developmental processes. Finally, the manner in which these topics are studied both in this special issue and elsewhere can be characterized in terms of three broad classifications (Commons & Bresette, 2000, Commons & Miller, 1998) for the acquisition of knowledge and the verification of truth in general. These classifications include analytic, experiential, and empirical means to reach truth.     

学习支持对儿童在多媒体语境中学习英语词汇的影响

该研究旨在考察中文翻译与主题提示两种学习支持对儿童在多媒体语境中学习英语词汇的作用,为此设计了三种学习条件：无支持条件、中文翻译条件和中文翻译 主题提示条件。对学龄初期儿童在上述三种学习条件下学习英语词汇的过程和结果进行的考察和分析表明：儿童在无支持条件下的学习效果较差;中文翻译可以明显促进儿童对语句的理解,但无法提高儿童对目标词的掌握;中文翻译 主题提示条件下儿童对单词语义的掌握最好,他们表现出了较多的跟读行为,并更倾向于认为学习任务较为容易。     

中学生知识获得过程是从情景记忆向语义记忆转化的过程

本研究探讨中学生的知识掌握过程。针对2001—2002年度上学期教学内容,对初中二年级学生的四门课程分别进行两次测验。对于每道选择题,学生首先选择正确答案,然后指出记忆的意识状态：记住的、知道的、猜测的。结果发现,学生记忆意识类型的转变(由记住向知道)取决于课程类型、保持时间和学生等级。对于不同课程,学生占优势的意识类型不同,自然学科知道的反应占优势,社会学科记住的反应占优势;优等生知道的反应多于其他学生;随着学习时间的延长,中学生的意识类型发生了由记住向知道的转变,这表明知识掌握过程中,中学生的知识表征发生了由情景记忆向语义记忆的转变。     

由知识对伦理的辩护到伦理对知识的批判——论知识的伦理价值

古希腊哲学最早将美德与知识相联系,“真”的达到就是“善”的实现,人的合目的性是建立在其合规律性的基础上的,伦理学从此有了独立存在的根据。近代知识论提出“知识就是力量”,将获得知识与获得幸福视为同一,知识(理性)是建立伦理的绝对普遍的坚实基础,人的尊严和主体性成为伦理追求的最大价值。20世纪以来,由于科学知识的异化,“知识与人的幸福和命运问题”凸现在当代伦理学面前。为知识找寻一条“应然”的光明之路,不仅是伦理学的理论使命,也是人类自身的神圣使命。     

背景知识对4~8岁儿童和大学生分类活动的影响

以4-8岁儿童和大学生为被试,用虚拟生物图片为材料,采用2(不提供背景知识和提供背景知识)×6(年龄)的实验设计,考察背景知识对被试分类活动的影响及其年龄特点。结果发现:(1)两种实验条件下均有显著的年龄差异。(2)提供背景知识与否对不同年龄被试分类活动的影响不同,对4-5岁儿童分类活动的影响不显著,对6-8岁儿童及大学生分类活动的影响显著。     

Chisholm's Epistemic Principles

Abstract: An exposition and discussion of Chisholm's “epistemic principles.” These are compared with relevant views of Wilfrid Sellars and Richard Foley. A further comparison, with the approach favored by Descartes, is argued to throw light on the status of such principles.
