数学焦虑对儿童加减法认知策略选择和执行的影响

根据数学焦虑量表测查结果,随机选取90名小学1~3年级的儿童为被试,每个年级30人(高、低数学焦虑者各15人).采用实验法、观察法和口语报告法相结合的方式,探讨不同数学焦虑水平儿童加减法认知策略选择和执行情况.结果发现:(1)从策略选择上看,高数学焦虑儿童使用出声策略和手势策略较多;使用对位策略较少.(2)从策略执行上看,高数学焦虑儿童出声策略、手势策略和拆十策略执行的正确率较高;竖式策略和对位策略执行的正确率较低;(3)随着儿童年级的增长,数学焦虑对其策略选择的影响越来越显著.

Effects of mood states on information processing strategies: Two studies of automatic and controlled processing using misattribution paradigms

To test the hypothesis that a positive mood facilitates automatic processing and a negative mood facilitates controlled processing, two experiments were conducted. In Experiment 1, after positive or negative mood was induced, participants rated the attractiveness of products while listening to a music tape that they were told would have the effect of inducing a positive, negative, or neutral mood. As predicted, augmentation effects were clearer in the negative mood condition than in the positive mood condition. In Experiment 2, participants were first presented with lists of names of non-famous Japanese companies either once or four times. One or two days later, they were presented with these names again, together with new names, and were asked to judge whether those names were famous or-non-famous. As predicted, subjects in a positive mood showed more false fame judgments than those in a negative mood because those in a positive mood did not control their feeling of familiarity correctly. These results indicated that those in positive moods are more likely to engage in automatic processing.     

关于阅读中的外显与内隐问题研究--兼谈高师英语阅读教学改革

目的：从新课程视角,探讨英语阅读中的外显与内隐问题,为阅读教学改革提供理论依据。方法：根据外显学习和内隐学习理论,对分析性阅读和概括性阅读进行分析比较,考察被试在分析性(外显的)和概括性(内隐的)阅读的时候,是如何“投射”出自己获取信息技能的过程的。结果：(1)阅读中存在着内隐现象且具有与外显性阅读相近的阅读成绩和效率;(2)各组被试阅读过程中未见有显著的性别差异;(3)外显阅读组和内隐阅读组均存在着特别显著的年级差异。结论：对于知识的吸收掌握和应用以及阅读能力的培养,外显阅读与内隐阅读各具有特色,互为补充,阅读教学中应充分认识到外显与内隐在阅读理解中的不同效果与作用。     

互惠教学:情境教学与认知教学结合的典范

互惠教学是一种教授阅读理解策略的教学模式,结合了专家示范教学与小组对话的特征。本文回顾了互惠教学这一教学模式的提出,以及在以往二十多年里这一领域所经历的策略研究、对话研究与教学情境研究的三个阶段;进而评价了以往研究中的不足。展望了今后研究的方向,为阅读策略的教学与研究提供了参考,并支持了专长研究的新视角。     

运动视觉中行为控制策略研究

当人穿越杂乱的环境到达一个目标时,可以利用多种信息源进行行为控制,这些信息既包括物理信息又包括视觉信息,人们有选择地利用各种信息或信息的整合控制计时行为。本文阐述了不同运动条件下如步行运动、拦截行为、飞行运动和驾驶运动观察者所使用的行为控制策略,这些控制策略与各种信息源密切相关并依赖于特定的任务。     

认知负荷理论在教学设计中的应用及其启示

在教学设计中,认知负荷理论有助于激励学习者的学习活动、使之表现出良好的学习绩效。认知负荷理论主要依赖于以容量有限的工作记忆为核心的认知结构的支持。工作记忆包括相对独立的视觉、听觉信息加工单元,同时又与容量较大的长时记忆共同承担着对信息的贮存与理解。根据该理论,可以通过把多个信息单元编码成一个完整的认知图式,或通过自动化加工规则,或使用多媒介（多感觉通路）呈现形式等多种方法来设法规避工作记忆的有限性。此文总结了可通过样例学习增加适当的认知负荷的教育技巧,样例一精细化训练对于降低认知干扰及超负荷的影响,样例对学习者的认知负荷的影响,以认知负荷理论为基础的教学设计原则,以及基于认知负荷理论研发的教学设计在各方面业已取得的进展及其存在的问题与可能的发展趋势。     

迎接医学人文学科发展的春天

我国医学人文学科的发展与我国的改革开放同步 ,在 2 0世纪 80年代末期到 90年代初曾经经历过一个发展高潮 ,但进入 90年代中期之后 ,随着第一批为我国医学人文学科建立作出卓越贡献的专家学者相继进入退休年龄而退出这一领域之后 ,医学人文科学的研究进入停滞阶段。今年SARS的发生暴露了我国公共卫生建设方面的失误 ,也引发了理论界的深刻反思。公共卫生投入不足、预防保健工作松软乏力 ,与我们对医学目的的认识以及卫生发展理论方面存在误区不无关系。由SARS所引发的公共卫生事件说明公共卫生决不是单纯的医学问题 ,它关系到国家的安全、影响到经济发展 ,需要从国家发展战略的角度来认识和全社会共同参与建设 ,这就为医学人文学科的发展提供了难得的契机     

Asymmetrical sample training produces asymmetrical retention functions in feature-present/feature-absent matching in pigeons

Pigeons were trained in a matching task in which samples involved presentation of a white line on a green background (feature-present) or on an otherwise dark key (feature-absent). After asymmetrical training in which one group was initially trained with the feature-present sample and another was initially trained with the feature-absent sample, marked retention asymmetries were obtained. In both groups, accuracy dropped precipitously on trials involving the initially trained sample and remained high on trials involving the sample introduced second in training. It was concluded that asymmetrical training encouraged a single-code/default strategy in which only the sample trained initially was coded. Consistent with this conclusion, changing attributes of either sample reduced accuracy to a greater extent in pigeons initially trained with that sample than in pigeons for which that sample was introduced second in training.     

Do university students’ thinking styles matter in their preferred teaching approaches?

This study pioneered the research on the role of university students’ thinking styles in their preferred teaching approaches. Three hundred and forty-eight (111 male and 237 female) students from a large comprehensive university in Beijing, P.R. China, responded to the Thinking Styles Inventory (Revised) and the Preferred Teaching Approach Inventory. Results indicated that regardless of age, gender, university class level, and academic discipline, students with different thinking styles had significantly different preferences for particular teaching approaches. It was contended that both conceptual change and information transmission are necessary for effective teaching. Theoretically, the study contributed to the styles literature in general and to the literature on the relationships between styles and approaches of teaching and learning in particular. Practical implications of the present findings are discussed in the context of students’ teaching evaluations, teachers’ teaching, and university administrators’ personnel management.
